Design of fault tolerant control technique for SRM drive

Abstract

This paper deals with the improvement of the switched reluctance motor's fault tolerant control for traction drives. The main purpose is to use a control technique which is able to retain the required speed for various load torques at minimal torque ripple also during one opened phase operation. The paper focuses on the comparative study of the current hysteresis control and direct instantaneous torque control (DITC) techniques.
