MACHINE’S CHARACTERISTICS IDENTIFICATION: A PRELIMINARY STUDY ON DIRECT TORQUE CONTROL FOR SWITCHED RELUCTANCE MOTOR DRIVES

The paper introduces direct torque control for switched reluctance motor drives. The main proposed ideas of this sensorless control are the development of non-linear torque equation, and the accurate identification of machine’s characteristics. These two factors are very crucial to the successful implementation of direct torque control in switched reluctance motors. A preliminary work done is the using of finite element analysis to find the machine’s characteristics of a commercially available 4-phase switched reluctance motor. The flux linkage and torque characteristics obtained are compared with the results from other journal papers. A certain degree of discrepancies between them have been found and analysed. 1. INRODUCTION Switched reluctance motor (SRM) has currently been given a considerable attention in the field of high-performance drives. The research work has globally been done in both industrial and university sectors. The machine has numerous advantages over othe
