Optimal phase current profiling of SRM by fuzzy logic controller to minimize torque ripple

Abstract

This paper presents torque ripple minimization of Switched Reluctance Motor (SRM) by using fuzzy speed controller. The nonlinear model of SRM is used and the motor used in simulation is a 8/6 SRM with C-Dump converter. The Fuzzy controller adjusts value of reference current to keep speed constant. The results show that the fuzzy logic is effective in reducing the torque ripple of the motor, and compensating for the nonlinear torque characteristics.
