Minimization of Torque – Ripple by using Novel Method Control in Switched Reluctance Motor

This Paper describes a novel method of Switched Reluctance Motor (SRM) drive system, using Sliding mode (SMC) this is proposed method and Proportional Integral (PI) Controller this is existing method. In this paper Torque ripple is a major drawback of switched reluctance motor drive system, which causes undesirable vibration and acoustic noise. The approach focuses on maximizing torque density and minimizing torque ripple considering stator and rotor geometry parameters. So we comparing the result of proposed(SMC) and existing method(PI). Based on analytical procedure is developed in Matlab to compute the value of inductance and average torque. Torque ripple is evaluated from the inductance ratio, which gives direct measure of the torque overlap of adjacent phases. The optimization procedure is tested on Four-Phase Switched Reluctance Motor (SRM). The result was analyzed and the proposed topologies were simulated using MATLAB/Simulink software package and the results were obtained. The computer simulation results support the proposed methods.
