Energy harvesting from vibration with alternate scavenging circuitry and tapered cantilever beam / Mehraeen, Shahab in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010)  

Public ISBD [article]  inIEEE transactions on industrial electronics > Vol. 57 N° 3 (Mars 2010) . - pp. 820 - 830 Titre : Energy harvesting from vibration with alternate scavenging circuitry and tapered cantilever beam Type de document : texte imprimé Auteurs : Mehraeen, Shahab, Auteur ; Jagannathan, S., Auteur ; Corzine, Keith A., Auteur Article en page(s) : pp. 820 - 830 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Cantilever beam Energy harvesting Piezoelectric Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : Piezoelectric transducers are increasingly being used to harvest energy from environmental vibrations in order to either power remote sensors or charge batteries that power the sensors. In this paper, a new voltage compensation scheme for high-voltage-based (> 100 V) energy harvesting is introduced, and its fundamental concepts, as well as the operation details, are elaborated. This scheme, when applied to the voltage inversion method [synchronized switch harvesting on inductor (SSHI)], provides an increase of over 14% in harvested power when compared to the parallel inversion method (parallel SSHI) alone and more than 50% in the case of series inversion method (series SSHI). Second, tapered cantilever beams were shown to be more effective in generating a uniform strain profile over rectangular and trapezoidal beams if they are precisely shaped, resulting in a significant increase in harvested power over available methods in the literature from laboratory experimental tests. In addition, a simplified method to design such a beam is introduced. Finally, a field test of the proposed tapered beam is conducted by using a dozer for earth-moving applications, and experimental results are discussed.

A low-power stand-alone adaptive circuit for harvesting energy from a piezoelectric micropower generator / Tabesh, Ahmadreza in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010)

Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : An adaptive energy-harvesting circuit with low power dissipation is presented and demonstrated, which is useful for efficient ac/dc voltage conversion of a piezoelectric micropower generator. The circuit operates stand-alone, and it extracts the piezoelectric strain energy independent of the load and piezoelectric parameters without using any external sensor. The circuit consists of a voltage-doubler rectifier, a step-down switching converter, and an analog controller operating with a single supply voltage in the range of 2.5-15 V. The controller uses the piezoelectric voltage as a feedback and regulates the rectified voltage to adaptively improve the extracted power. The nonscalable power dissipation of the controller unit is less than 0.05 mW, and the efficiency of the circuit is about 60% for output power levels above 0.5 mW. Experimental verifications of the circuit show the following: 1) the circuit notably increases the extracted power from a piezoelectric element compared to a simple full-bridge diode rectifier without control circuitry, and 2) the efficiency of the circuit is dominantly determined by its switching converter. The simplicity of the circuit facilitates the development of efficient piezoelectric energy harvesters for low-power applications such as wireless sensors and portable devices.

Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper presents a solution for energy microgeneration through energy harvesting by taking advantage of temperature differences that are converted into electrical energy using the Seebeck effect. A thermoelectric microconverter for energy scavenging systems that can supply low-power electronics was fabricated using thin films of bismuth and antimony tellurides. Thin films of n-type bismuth (Bi2Te3) and p-type antimony (Sb2Te3) tellurides were obtained by thermal coevaporation with thermoelectric figures of merit (ZT) at room temperature of 0.84 and 0.5 and power factors (PF × 10-3 [W · K-1 ·m-2]) of 4.87 and 2.81, respectively. The films were patterned by photolithography and wet-etching techniques. The goal for this thermoelectric microconverter is to supply individual electroencephalogram (EEG) modules composed by an electrode, processing electronics, and an antenna, where the power consumption ranges from hundredths of microwatts to a few milliwatts. Moreover, these wireless EEG modules allow patients to maintain their mobility while simultaneously having their electrical brain activity monitored.

Accurate power loss model derivation of a high-current dual active bridge converter for an automotive application / Krismer, Florian in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010)

Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : An accurate power loss model for a high-efficiency dual active bridge converter, which provides a bidirectional electrical interface between a 12-V battery and a high-voltage (HV) dc bus in a fuel cell car, is derived. The nominal power is 2 kW, the HV dc bus varies between 240 and 450 V, and the battery voltage range is between 11 and 16 V. Consequently, battery currents of up to 200 A occur at nominal power. In automotive applications, high converter efficiency and high power densities are required. Thus, it is necessary to accurately predict the dissipated power for each power component in order to identify and to properly design the heavily loaded parts of the converter. In combination with measured efficiency values, it is shown that conventional converter analysis predicts substantially inaccurate efficiencies for the given converter. This paper describes the main reasons why the conventional method fails and documents the different steps required to predict the power losses more accurately. With the presented converter prototype, an efficiency of more than 92% is achieved at an output power of 2 kW in a wide input/output voltage range.

Hybrid cascaded H-bridge multilevel-inverter induction-motor-drive direct torque control for automotive applications / Khoucha, Farid in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010)

Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper presents a hybrid cascaded H-bridge multilevel motor drive direct torque control (DTC) scheme for electric vehicles (EVs) or hybrid EVs. The control method is based on DTC operating principles. The stator voltage vector reference is computed from the stator flux and torque errors imposed by the flux and torque controllers. This voltage reference is then generated using a hybrid cascaded H-bridge multilevel inverter, where each phase of the inverter can be implemented using a dc source, which would be available from fuel cells, batteries, or ultracapacitors. This inverter provides nearly sinusoidal voltages with very low distortion, even without filtering, using fewer switching devices. In addition, the multilevel inverter can generate a high and fixed switching frequency output voltage with fewer switching losses, since only the small power cells of the inverter operate at a high switching rate. Therefore, a high performance and also efficient torque and flux controllers are obtained, enabling a DTC solution for multilevel-inverter-powered motor drives.

Tubes à rayons X Résumé : This paper presents a hybrid cascaded H-bridge multilevel motor drive direct torque control (DTC) scheme for electric vehicles (EVs) or hybrid EVs. The control method is based on DTC operating principles. The stator voltage vector reference is computed from the stator flux and torque errors imposed by the flux and torque controllers. This voltage reference is then generated using a hybrid cascaded H-bridge multilevel inverter, where each phase of the inverter can be implemented using a dc source, which would be available from fuel cells, batteries, or ultracapacitors. This inverter provides nearly sinusoidal voltages with very low distortion, even without filtering, using fewer switching devices. In addition, the multilevel inverter can generate a high and fixed switching frequency output voltage with fewer switching losses, since only the small power cells of the inverter operate at a high switching rate. Therefore, a high performance and also efficient torque and flux controllers are obtained, enabling a DTC solution for multilevel-inverter-powered motor drives.

A multiobjective parametric optimization for passenger-car steering actuator / Choi, Hae-Ryong in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010)

Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : A robust design for the size optimization of a motor-driven steer applied in a compact car, using the design of simulation trial, is described and illustrated in this paper. The objective of the optimal design using the combined design of simulation trial and finite-element analysis (FEA) approach is to ensure that the motor-driven steer's performance for compact cars is insensitive to noise, with moderate computational effort. The optimal design process takes into consideration noises that arise in the unexpected load condition, such as tolerances for parameter variation of the electric motor and reduction gear in the actuator. The optimization is realized by a simulation and analysis tool that integrates the Target-wise Parameter Optimization and the FEA. The proposed procedure can not only reduce the size of an actuator but also raise the system efficiency of the motor-driven steering (MDS). In this paper, we have used an orthogonal array L18(21 x 37) to implement simulation trials and made a response table and graph of control factors. Eventually, the optimal values of the control factors, the diameter of the stator core, the width of the wire, the turn number of the wire, the gear ratio of the worm and worm-wheel gear, the surface flux density of the magnet, the armature core's stack factor, and the module ratio of the worm and worm-wheel gear were decided, and then, the signal-to-noise ratio (SNR) was increased to 20.58%. The simulation results demonstrated that the proposed method applied to the optimal design of the MDS' actuator was feasible and efficient. In this paper, the design optimization process is described, and the results are presented.

On lead-acid-battery resistance and cranking-capability estimation / Cugnet, Mikael in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010)

Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : With hybrid and electric vehicle developments, battery-monitoring systems have to meet the new requirements of the automobile industry. This paper deals with one of them, the battery's ability to start a vehicle, also called battery crankability, through battery-resistance estimation. A fractional-order model obtained by system identification is used to estimate the internal resistance of lead-acid batteries. Fractional-order modeling permits an accurate simulation of the battery electrical behavior with a low number of parameters. Moreover, the high-frequency gain of the fractional model is directly linked to the battery resistance. A resistance-estimation method based on a frequency-invalidation method is, thus, proposed. It is demonstrated that the battery's available power that defines battery crankability is correlated to the battery resistance. Thus, a battery-crankability estimator using the battery resistance is suggested. Validation tests are carried out with various batteries. This estimator cannot be embedded in a microcontroller due to the linear-matrix-inequality-based optimization algorithm in the invalidation-model method used. A simplified algorithm is finally proposed, and its efficiency is proved.

A study of a hybrid filter / Ostroznik, S. in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010)

Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper presents results of a comparative study of two possible hybrid filter topologies, comprised of a passive and active stage, which can be implemented in any general dc supply distribution system. The main filter task is to mitigate current dynamics in the dc distribution system in order to prolong the operational life of delicate dc supplies, i.e., fuel cells, and to reduce the electromagnetic interferences between sensitive electronic circuits connected to the distribution net. The active stage is incorporated into the passive part in order to: 1) improve its insufficient attenuation in the low-frequency range and 2) source or sink any surplus energy flow between the dc source and load in case of low-frequency current dynamics. Two active stage topologies are proposed, analyzed, and evaluated in detail: 1) an active filter based on a single-leg inverter and 2) an active filter based on an electronic smoothing inductor. A special focus is on achieving attenuation at different voltage levels of the auxiliary supply and at different coupling inductances. The impact of the current ripple generated by the switching mode of the active filter operation is discussed as well. The active filter based on the single-leg inverter offers superior attenuation, particularly in the low-frequency range where attenuation is improved nearly for 15 dB compared to the passive filter.

Electric vehicle using a combination of ultracapacitors and ZEBRA battery / Dixon, Juan in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010)

Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : The sodium-nickel chloride battery, commonly known as ZEBRA, has been used for an experimental electric vehicle (EV). These batteries are cheaper than Li-ion cells and have a comparable specific energy (in watt-hours per kilogram), but one important limitation is their poor specific power (in watts per kilogram). The main objective of this paper is to demonstrate experimentally that the combination of ZEBRA batteries and ultracapacitors (UCAPs) can solve the lack of specific power, allowing an excellent performance in both acceleration and regenerative braking in an EV. The UCAP system was connected to the ZEBRA battery and to the traction inverter through a buck-boost-type dc-dc converter, which manages the energy flow with the help of DSP controllers. The vehicle uses a brushless dc motor with a nominal power of 32 kW and a peak power of 53 kW. The control system measures and stores the following parameters: battery voltage, car speed to adjust the energy stored in the UCAPs, instantaneous currents in both terminals (battery and UCAPs), and present voltage of the UCAP. The increase in range with UCAPs results in more than 16% in city tests, where the application of this type of vehicle is being oriented. The results also show that this alternative is cheaper than Li-ion powered electric cars.

Tubes à rayons X Résumé : This paper presents a new predictive current control for three-phase grid-connected inverters in the synchronous reference frame. The control combines a deadbeat control law with a diagonal Luenberger observer to estimate the future value of the grid currents. It provides a decoupled control of the active and reactive power and offers robustness against the computational delay inherent in the digital implementation and against filter and grid-impedance uncertainties. This control exhibits a very fast current response while widely improving the gain and phase margins of the traditional predictive controllers.

It provides a decoupled control of the active and reactive power and offers robustness against the computational delay inherent in the digital implementation and against filter and grid-impedance uncertainties. This control exhibits a very fast current response while widely improving the gain and phase margins of the traditional predictive controllers.

Tubes à rayons X Résumé : In this paper, a feedback linearization technique is proposed to control the output voltage control of three-phase uninterruptible power supply systems. First, a nonlinear model including the output LC filters is derived from the power balance condition between the inverter output terminal and the load side. Then, input-output feedback linearization is applied to the nonlinear model to make it linear. The controller of the linearized model is designed by linear control theory. The tracking control law is obtained with a pole placement technique. It is shown experimentally that the proposed control scheme gives high dynamic responses in response to load variation as well as a zero steady-state error.

Torque feedforward control technique for permanent-magnet synchronous motors / Bing, Cheng in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010)

Tubes à rayons X Résumé : This paper proposes a torque control method for interior permanent-magnet (IPM) motors operating in a wide speed range requiring high torque/power accuracy and a fast dynamic response. Using the fact that the motor parameters are nonlinear and significantly vary with direct and quadrature current operating points, a new optimal operating plane is generated. This operating plane combines the maximum torque per ampere (MTPA) curve, current limit circle, and maximum torque per volt (MTPV) curve, voltage limitations, and torque calculation under the nonlinear parameter variations. As a result, new feedforward tables are generated, which make full use of measured motor parameters. The new torque and flux regulators built around the feedforward tables provide a fast dynamic response and accurate steady-state torque/power production. The proposed controller was implemented and successfully tested on a 105-kW IPM motor electric drive used in a fuel-cell vehicle program.

Adaptive nonlinear direct torque control of sensorless IM drives with efficiency optimization / Hajian, M. in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010)

Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : Efficiency optimization of induction motor (IM) drives is a major subject based on these drives' extensive use in the industry. Among the different proposed methods, a model-based approach (MBA) seems to be the fast one. However, this method needs the motor parameters that must be correctly identified. On the other hand, a search-based approach (SBA) is a parameter-independent method but needs a greater convergence time. In this paper, a novel model-based loss-minimization approach is presented, which is combined with a backstepping direct torque control of the IM drive. An improved search-based method for efficiency optimization is also introduced. The proposed controller is realized in the stationary reference frame and has a fast-tracking capability of rotor flux and electromagnetic torque. Moreover, a sliding-mode rotor-flux observer is introduced, which is employed for simultaneous determination of rotor-flux space vector, rotor speed, and rotor time constant. The proposed control idea is experimentally implemented in real time using a field-programmable gate-array board synchronized with a personal computer. Simulation and experimental results are finally presented to verify the effectiveness of the method proposed.

Tubes à rayons X Résumé : In recent research, a field reconstruction (FR) technique was developed to enable more efficient evaluation of the magnetic fields and forces within induction machines. By using the FR, the results of two finite-element (FE) solutions (in which stator current is used as the input to the FE model) are used to establish basis functions for the flux densities in the air gap of the machine. The basis functions are then used to predict the magnetic fields and forces under arbitrary stator excitation. In this paper, the technique is enhanced to enable modeling with stator voltage (rather than stator current) as the model input. This enables a more convenient coupling of the FR model to external circuit components to model overall system performance.

SRs are widely used in switched-mode power supplies with low output voltage and high output current for efficiency improvement. Owing to the high-efficiency characteristic, it is adequate to use an SR buck converter in a voltage regulator for powering a central processing unit.

Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : A zero-voltage- and zero-current-switching full-bridge (FB) converter with secondary resonance is presented and analyzed. The primary side of the converter is composed of FB insulated-gate bipolar transistors, which are driven by phase-shift control. The secondary side is composed of a resonant tank and a half-wave rectifier. Without an auxiliary circuit, zero-voltage switching (for leading-leg switches) and zero-current switching (for lagging-leg switches) are achieved in the entire operating range. To implement the converter without an additional inductor, the leakage inductance of the transformer is utilized as the resonant inductor. Due to its many advantages, including high efficiency, minimum number of devices, and low cost, this converter is attractive for high-voltage and high-power applications. The analysis and design considerations of the converter are presented. A prototype was implemented for an application requiring a 5-kW output power, an input-voltage range varying from 250 to 350 V, and a 350-V output voltage. The experimental results obtained from a prototype verify the analysis. The prototype's efficiency at full load is over 95.5%.

Steady-state analysis and passivity-based control of single-phase PWM current-source inverters / Komurcugil, Hasan in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010)

Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper proposes a passivity-based control (PBC) strategy for single-phase pulsewidth-modulated current-source inverters feeding a resistive load. In this strategy, it is required to estimate the load resistance and the inductor-current reference. However, the estimation accuracy depends on the inductance value when the load resistance and the inductor-current reference are estimated using an existing adaptive algorithm. In this paper, it is shown that the inductor-current reference estimation is possible at the expense of a constant reference function for the inductor current. In addition, the design of inductor and the sensitivity of the output voltage to the value of output capacitor used in the controller are studied extensively through the steady-state analysis of the proposed PBC. It is also shown that even very large values of the estimation error do not give rise to significant change in the output-voltage amplitude.

Tubes à rayons X Résumé : This paper proposes a passivity-based control (PBC) strategy for single-phase pulsewidth-modulated current-source inverters feeding a resistive load. In this strategy, it is required to estimate the load resistance and the inductor-current reference. However, the estimation accuracy depends on the inductance value when the load resistance and the inductor-current reference are estimated using an existing adaptive algorithm. In this paper, it is shown that the inductor-current reference estimation is possible at the expense of a constant reference function for the inductor current. In addition, the design of inductor and the sensitivity of the output voltage to the value of output capacitor used in the controller are studied extensively through the steady-state analysis of the proposed PBC. It is also shown that even very large values of the estimation error do not give rise to significant change in the output-voltage amplitude. Computer simulations and experiments are presented to verify the theoretical considerations.

Tubes à rayons X Résumé : The design of electromagnetic interference (EMI) input filters, needed for switched power converters to fulfill the regulatory standards, is typically associated with high development effort. This paper presents a guideline for a simplified differential-mode (DM) filter design. First, a procedure to estimate the required filter attenuation based on the total input rms current using only a few equations is given. Second, a volume optimization of the needed DM filter based on the previously calculated filter attenuation and volumetric component parameters is introduced. It is shown that a minimal volume can be found for a certain optimal number of filter stages. The considerations are exemplified for two single-phase power factor correction converters operated in continuous and discontinuous conduction modes, respectively. Finally, EMI measurements done with a 300-W power converter prototype prove the proposed filter design method.

Flyback-based single-stage power-factor-correction scheme with time-multiplexing control / Jun Zhang in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010)

Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : A flyback-based single-stage power-factor-correction scheme with time-multiplexing control (TMC) is proposed. As a portion of the input power will be transferred to the output after the first power processing to improve the conversion efficiency, the output voltage would contain substantial low-frequency ripple. An isolated auxiliary circuit based on forward topology is therefore added to the converter to serve as a buffer and a ripple suppression circuit. With TMC, all the power processes can be achieved by a single transformer to lower the size and cost of the converter. In addition, the proposed converter inherits bulk capacitor (auxiliary) voltage clamping capability. The experimental results confirmed the effectiveness of the proposed scheme with high power factor, natural bulk capacitor (auxiliary) clamping voltage, and tight output regulation.

Time-delay compensation by communication disturbance observer for bilateral teleoperation under time-varying delay / Natori, Kenji in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010)

Tubes à rayons X Résumé : This paper presents the effectiveness of a time-delay compensation method based on the concept of network disturbance and communication disturbance observer for bilateral teleoperation systems under time-varying delay. The most efficient feature of the compensation method is that it works without time-delay models (model-based time-delay compensation approaches like Smith predictor usually need time-delay models). Therefore, the method is expected to be widely applied to network-based control systems, in which time delay is usually unknown and time varying. In this paper, the validity of the time-delay compensation method in the cases of both constant delay and time-varying delay is verified by experimental results compared with Smith predictor.

Development of robust starting system using sensorless vector drive for a microturbine / Rho, Min-Sik in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010)  

Public ISBD [article]  inIEEE transactions on industrial electronics > Vol. 57 N° 3 (Mars 2010) . - pp. 1063 - 1073 Titre : Development of robust starting system using sensorless vector drive for a microturbine Type de document : texte imprimé Auteurs : Rho, Min-Sik, Auteur ; Kim, Sam-Young, Auteur Article en page(s) : pp. 1063 - 1073 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Microturbine (MT) Sensorless vector control Single shaft Starter Starting algorithm Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper presents the development of a robust starting system for a microturbine (MT) with a single-shaft structure. Because the operating speed for the ignition and motoring of an MT is close to several tens of thousands of revolutions per minute, stable high-speed operation of the high-speed motor-generator (HSMG) is a critical issue in realizing a starting system for a single shaft. A sensorless vector inverter was developed for this high-speed operation. To successfully start an MT with the developed starter in practice, two new starting algorithms were proposed. One is a constant power output control algorithm that can maintain a perfect motoring schedule with significantly deteriorated performance of the input battery power in a vehicle under an extremely low temperature and severe engine drag. The other is a new reliable ignition verification logic that uses the inverter output current when the exhausted gas temperature sensor does not work properly. Since the two proposed algorithms are derived from the torque and q-axis current formulas for the vector drive, no additional hardware is required to apply them to an existing MT. In this paper, a single-shaft MT with a 10-kW inverter, 6-kW booster converter, and 25-kW HSMG was developed, and the proposed algorithms were applied to motoring. To verify the performance of the proposed algorithms, experiments were carried out under variable conditions, such as extremely low temperature (-32°C) and room temperature. The MT has used in a military truck for supplying electrical power and bleeding air.

Tubes à rayons X Résumé : This paper presents a tactile sensor system for a robot manipulator and an active-sensing technique to realize 3-D object recognitions concerning object shape, object surface normal, and object edge tracing with experimental results. The proposed tactile sensor units implemented on the robot hand consist of three thin sheets of force-sensitive resistors arranged triangularly with the peripheral circuits. One potential application of the proposed techniques is to realize an effective human-robot cooperation to move an object together by utilizing the control of a hand pose to keep the direction of the hand normal to the object surface in three dimensions, which is often necessary when pushing an object. Another is a 3-D object edge tracing. The proposed techniques can be employed in industrial processes such as welding and inspection to eliminate manual teaching procedures for searching the object edge automatically before doing the welding process. In these applications, information about the object shape or orientation is not required in advance.

Tubes à rayons X Résumé : This paper presents a new methodology for designing and implementing position control for permanent-magnet linear synchronous motor (PMLSM) systems. We utilize both a new function-based sliding-mode control (SMC) method and direct thrust control (DTC). It has been established that chattering is a problem in conventional SMC and stems from discontinuous control. However, the new function-based controller allows designers to employ fuzzy membership functions directly. The advantage of the proposed method is that the chattering phenomenon can be reduced and/or completely eliminated. The design of the control method for the proposed system can be performed without the need for great expertise as it does not require the use of very complicated techniques. It should be noted that we have managed to control the inherent flux linkage problems associated with PMLSMs. To our knowledge, this is the first work that combines the new SMC with DTC techniques in order to create a position control for a real-world PMLSM. Simulation and experimental results verify that the proposed method can achieve favorable control performance with regard to parameter variations and external disturbances.

A nonlinear phenomenon on self-oscillating current controllers: the indirect synchronization / Olivier, Jean-Christophe in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010)

This phenomenon appears in medium frequencies, when the reference signal frequency tends to the switching frequency. In a previous work, it has been shown that the indirect synchronization causes discontinuities on the frequential response of the system, making the various linear or continuous models inefficient. For high-accuracy applications, such as active filtering or high-precision power supply, these discontinuities are a real problem. Thus, it seems important to offer an analytical description of this phenomenon. In this paper, an analytical model of the indirect synchronization phenomenon is proposed and checked by simulation and experimental results.

Public ISBD [article]  inIEEE transactions on industrial electronics > Vol. 57 N° 3 (Mars 2010) . - pp. 1112 - 1119 Titre : Equipment design and control of advanced thermal-processing module in lithography Type de document : texte imprimé Auteurs : Tay, Arthur, Auteur ; Chua, Hui Tong, Auteur ; Wang, Yuheng, Auteur Article en page(s) : pp. 1112 - 1119 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Lithography Temperature control Thermal cycling Thermoelectric Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : A programmable multizone thermal-processing module is developed to achieve wafer-temperature uniformity during the thermal-cycling process in lithography. The bake and chill steps are conducted sequentially within the same module without any substrate movement. An array of thermoelectric devices (TEDs) is used to provide a distributed heating to the substrate for uniformity and transient temperature control. The TEDs also provide active cooling for chilling the substrate to a temperature suitable for subsequent processing steps. This design is an improvement of a previous work, eliminating the need of a mica heater. The system is designed via detailed modeling and simulations based on first-principle heat-transfer analysis. Experimental results on the prototype demonstrate about ±0.4°C spatial uniformity during the entire thermal cycle.

Dynamic surface profilometry and resonant-mode detection for microstructure characterization using nonconventional stroboscopic interferometry / Chen, Liang-Chia in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010)  

Public ISBD [article]  inIEEE transactions on industrial electronics > Vol. 57 N° 3 (Mars 2010) . - pp. 1120 - 1126 Titre : Dynamic surface profilometry and resonant-mode detection for microstructure characterization using nonconventional stroboscopic interferometry Type de document : texte imprimé Auteurs : Chen, Liang-Chia, Auteur ; Nguyen, Xuan-Loc, Auteur ; Huang, Hsin-Sing, Auteur Article en page(s) : pp. 1120 - 1126 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Dynamic profilometry Microelectromechanical systems (MEMS) Resonant mode Stroboscopic interferometry Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : In this paper, an innovative method of automatic resonant-mode detection employing nonconventional stroboscopic interferometry is developed for nanoscale dynamic characterization of microstructures. Considering that a tested microstructure having an individual vibrating excitation source cannot be analyzed directly by the traditional stroboscopic method, an optical microscopy based on new stroboscopic interferometry was established to achieve resonant-mode detection and full-field vibratory out-of-plane surface profilometry of microstructures. To verify the effectiveness of the developed methodology, a crossbridge microbeam was measured to analyze the resonant vibratory modes and full-field dynamic-mode characterization. The experimental results confirm that the dynamic behavior of the microstructures can be accurately characterized with satisfactory mode-detection accuracy and surface profilometry.

S., Auteur ; Man, K. F., Auteur Article en page(s) : pp. 1127 - 1131 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Biological neural network (BNN) Genetic algorithms (GAs) Identification Optimization methods Résumé : Recently, the identification of biological neural networks has been reformulated as an optimization problem based on a framework of adaptive synchronization. In this paper, four different optimization algorithms, including genetic algorithm, jumping gene genetic algorithm (JGGA), tabu search, and simulated annealing, have been applied for this optimization problem. Based on the simulation results, their performances are compared, and it is concluded that JGGA can outperform the other three methods in term of minimizing the synchronization and parameter estimation errors.
