Control and implementation of a matrix-converter-based AC ground power-supply unit for aircraft servicing / Lopez Arevalo, Saùl in IEEE transactions on industrial electronics, Vol. 57 N° 6 (Juin 2010) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 6 (Juin 2010) . - pp. 2076 - 2084 Titre : Control and implementation of a matrix-converter-based AC ground power-supply unit for aircraft servicing Type de document : texte imprimé Auteurs : Lopez Arevalo, Saùl, Auteur ; Zanchetta, Pericle, Auteur ; Wheeler, Patrick W., Auteur Article en page(s) : pp. 2076 - 2084 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Matrix  converter  Power  supplies  Repetitive  control Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper deals with the design, control, and implementation of a three-phase ground power-supply unit for aircraft servicing. Instead of a classical back-to-back converter configuration, a three-phase direct ac-ac (matrix) converter has been used as the power conditioning core of the power supply, working in conjunction with input and output LC filters. An optimized control system in the ABC frame employing a repetitive controller has been successfully implemented, taking into account both the transient and steady-state performance targets together with the system effectiveness under extreme unbalanced conditions. Extensive experimental tests on a 7.5-kVA prototype prove the efficiency of the designed system in meeting the high demanding civil and military international standards requirements.

Real-time estimation of fundamental frequency and harmonics for active shunt power filters in aircraft electrical systems / Lavopa, Elisabetta in IEEE transactions on industrial electronics, Vol. 56 N° 8 (Août 2009) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 56 N° 8 (Août 2009) . - pp. 2875 - 2884 Titre : Real-time estimation of fundamental frequency and harmonics for active shunt power filters in aircraft electrical systems Type de document : texte imprimé Auteurs : Lavopa, Elisabetta, Auteur ; Zanchetta, Pericle, Auteur ; Mark Sumner, Auteur Article en page(s) : pp. 2875 - 2884 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Active  filters  Frequency  estimation  Harmonic  analysis  More  electric  aircraft  Power  quality Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : A novel algorithm for fundamental frequency and harmonic components detection is presented in this paper. The technique is based on a real-time implementation of discrete Fourier transform, and it allows fast and accurate estimation of fundamental frequency and harmonics of a distorted signal with variable fundamental frequency. It is suitable for active shunt filter applications, when fast and accurate tracking of the reference signal is required to achieve a good control performance. The main application for the algorithm is aircraft ac power systems, where the fundamental frequency can be either fixed on 400 Hz and its actual value fluctuates around the nominal value, or variable in the range 360-900 Hz. Hence, a real-time estimation of fundamental frequency is essential for active filter control. The proposed algorithm has been at first implemented in Matlab/Simulink for computer simulation, and it has been compared with a Phase Locked Loop (PLL) algorithm for frequency detection and the synchronous dq reference method for harmonic detection. Experimental tests have been carried out in order to validate the simulation results. The distorted current absorbed by a nonlinear load is analyzed and processed by means of a digital implementation of the algorithm running on the active shunt power filter control DSP, in order to calculate the active filter compensating current.

The use of genetic algorithms for the design of resonant compensators for active filters / Lenwari, Wanchak in IEEE transactions on industrial electronics, Vol. 56 N° 8 (Août 2009) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 56 N° 8 (Août 2009) . - pp. 2852 - 2861 Titre : The use of genetic algorithms for the design of resonant compensators for active filters Type de document : texte imprimé Auteurs : Lenwari, Wanchak, Auteur ; Mark Sumner, Auteur ; Zanchetta, Pericle, Auteur Article en page(s) : pp. 2852 - 2861 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Resonant  compensators  Genetic  algorithms  Active  power  filter  control Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : Resonant compensators appear to be suitable for active power filter control, where the compensator needs to track harmonic currents accurately. However, to ensure stable operation and robustness to parameter uncertainties they require considerable design effort. This paper describes the use of a genetic algorithm for the optimization of the parameters of a resonant controller employed for the control of current in a shunt active filter. The optimization process takes into account variations of the power system parameters to provide an optimum solution in terms of both speed of response and robustness. Experimental results confirm the effectiveness to the approach.
