Abstract: This paper deals with the analysis, study and modeling of the torque ripple minimization setup for the closed loop control of Switched Reluctance Motor.SRM is becoming more and more popular for high speed industrial application environments due to its rugged and robust construction. For low cost, variable speed drives SRM are most widely used. But the torque pulsations in SRM are relatively higher compared to sinusoidal machines due to the doubly salient structure of the motor. Nonlinear inductance profile and pulse magnetizing make the torque ripple unavoidable. Both machine design and electronic control approaches have been used to minimize the torque ripples in SRM. This paper gives an extensive review of the origin of the torque ripple and approaches adopted to minimize the torque ripple.The mathematical modeling of three phase SRM is developed and integrated with different converter topologies in Matlab / Simulink environment along with control methods. The power spectrum density wave forms of torque are studied to verify the simulation results obtained.
