Adaptive input–output feedback-linearization-based torque control of synchronous reluctance motor without mechanical sensor / Abootorabi Zarchi, Hossein in IEEE transactions on industrial electronics, Vol. 57 N° 1 (Janvier 2010) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 1 (Janvier 2010) . - pp. 375 - 384 Titre : Adaptive input–output feedback-linearization-based torque control of synchronous reluctance motor without mechanical sensor Type de document : texte imprimé Auteurs : Abootorabi Zarchi, Hossein, Auteur ; Soltani, Jafar, Auteur ; Markadeh, Gholamreza Arab, Auteur Article en page(s) : pp. 375 - 384 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Adaptive  input-output  feedback  linearization  (AIOFL)  Encoderless  Synchronous  reluctance  motor  (SynRM) Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : In this paper, a well-known adaptive input-output feedback-linearization (AIOFL) technique is used for speed and torque-tracking control of synchronous reluctance motor drive. This controller is capable of estimating motor two-axis inductances (Ld, Lq) simultaneously. The overall stability of the proposed control and the persistency of excitation condition are proved based on Lyapunov theory. In addition, the maximum rate of change of torque control scheme is applied to generate the motor d- and q-axis reference currents which are needed for AIOFL controllers. Another contribution of this paper is to estimate the rotor speed and position. For low-speed estimation, we have to eliminate the current and voltage sensors' dc offsets, detect the stator resistance, and take into account the voltage drop of the inverter power switches. We solve these problems by using a simple technique for eliminating the voltage sensors and a simple method for online estimation of the stator resistance and modeling the voltage drop of the inverter power switches. It is worthwhile to mention that the current sensors' dc offsets, seen on the measured currents, are negligible. Finally, the validity of the proposed method is verified by experimental results.

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) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 3 (Mars 2010) . - pp. 975 - 985 Titre : Adaptive nonlinear direct torque control of sensorless IM drives with efficiency optimization Type de document : texte imprimé Auteurs : Hajian, M., Auteur ; Soltani, Jafar, Auteur ; Markadeh, Gholamreza Arab, Auteur Article en page(s) : pp. 975 - 985 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Direct  torque  control  (DTC)  Efficiency  optimization  Induction  motor  (IM)  Integrator  backstrepping  Rotor  flux  Sliding  mode  (SM) Index. décimale : 621.38 Dispositifs électroniques. 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.
