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.
