Combined flux observer with signal injection enhancement for wide speed range sensorless direct torque control of IPMSM drives / Andreescu, G. in IEEE transactions on energy conversion, Vol. 23 n°2 (Juin 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°2 (Juin 2008) . - pp. 393 - 402 Titre : Combined flux observer with signal injection enhancement for wide speed range sensorless direct torque control of IPMSM drives Type de document : texte imprimé Auteurs : Andreescu, G., Auteur ; Pitic, C.I., Auteur ; Blaabjerg, F., Auteur Année de publication : 2008 Article en page(s) : pp. 393 - 402 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Permanent  magnet  motors;  rotors;  synchronous  motor  drives;  torque  control Résumé : This paper proposes a motion-sensorless control system using direct torque control with space vector modulation for interior permanent magnet synchronous motor (IPMSM) drives, for wide speed range operation, including standstill. A novel stator flux observer with variable structure uses a combined voltage-current model with PI compensator for low-speed operations. As speed increases, the observer switches gradually to a PI compensated closed-loop voltage model, which is solely used at high speeds. High-frequency rotating-voltage injection with a single D-module bandpass vector filter and a phase-locked loop state observer with a new synchronization procedure are used to estimate the rotor position, which is needed only by the current model in stator flux observer at low speeds. A new rotor speed estimator for the whole speed-loop range, based on the stator flux speed estimation with a new dynamic correction depending on estimated torque, is proposed and tested. Extensive simulation results and significant experimental results provided good performance for the proposed IPMSM sensorless system in more than 1:1000 speed range, under full-load operation, from very low speeds (1 r/min experimental) up to rated speed.

Simple power control for sensorless induction motor drives fed by a matrix converter / Kyo-Beum Lee in IEEE transactions on energy conversion, Vol. 23 n°3 (Septembre 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°3 (Septembre 2008) . - pp. 781 - 788 Titre : Simple power control for sensorless induction motor drives fed by a matrix converter Type de document : texte imprimé Auteurs : Kyo-Beum Lee, Auteur ; Blaabjerg, F., Auteur Année de publication : 2008 Article en page(s) : pp. 781 - 788 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Induction  motor  drives;  machine  control;  matrix  convertors;  power  control;  switching  convertors Résumé : This paper presents a new and simple method for sensorless control of matrix converter drives using a power flowing to the motor. The proposed control algorithm is based on controlling the instantaneous real and imaginary powers into the induction motor. To improve low-speed sensorless performance, the nonlinearities of a matrix converter drive such as commutation delays, turn-ON and turn-OFF times of switching devices, and on-state switching device voltage drop are modeled using a PQ power transformation and compensated using a reference power control scheme. The proposed sensorless control method is applied for the induction motor drive using a 3 kW matrix converter system. Experimental results are shown to illustrate the feasibility of the proposed strategy.
