Investigation of green powered optimized intelligent controllers for sensorless control of switched reluctance motor

Abstract

Simple structure, high speed, low cost, reliable and robust construction attracts the vision of researchers on Switched Reluctance Motor (SRM) drives. It is self-starting, simple stator to wind and there is no possibility for phase to phase crossover faults. It has high starting torque without heavy inrush currents. Rotor carries no windings, no brushes, so the SRM requires less maintenance. These advantages are welcomed for the domestic applications like vacuum cleaners, washing machines, food processors, automobiles, general purpose electrical drives etc. Performance of SRM drive using rotor position transducers have many disadvantages like cost, connection, alignment mismatch, less suitability to space restricted applications. These drawbacks of sensors have been motivated for the development of sensorless techniques in the recent years. The vulnerable factors are need of rotor position feedback, speed fluctuations and torque ripples under high speed. These issues need to be sort out for optimal control and high performance of SRM drive. newline
