—Fuzzy logic-based on-line efficiency optimization control has been described in the literature [1] for an indirect vector-controlled induction motor drive. The purpose of this paper is to extend the same control to a stator flux-oriented electric vehicle induction motor drive and then implement the fuzzy controller by a dynamic back propagation neural(More)
Preface The results presented in this thesis have been elaborated during my time at the " Laboratoire d'Electronique Industrielle " directed by Prof. A. Rufer. The project was financed through support from the Swiss Federal Office of Energy. I would like to take this opportunity to express my gratitude to everyone who contributed to making it all possible.(More)
—This letter describes a zero-speed start-up method of a speed sensorless stator-flux-oriented direct vector-controlled induction motor drive with the help of a machine current model that does not use any speed signal. The machine starts smoothly with vector control at finite developed torque and then transitions to the standard direct vector-control mode(More)
