Abstract: Large torque ripple of the Switched Reluctance Motor (SRM) is a major problem that is an obstacle to spreading over an industry. Nonlinear inductance profile and pulse magnetizing make the torque ripple unavoidable. In order to reduce the torque ripple, it is necessary to control the torque directly because the torque of the SRM is not linearly proportional to a current. This paper shows direct torque control scheme that reduces the torque ripple of the SRM dramatically. To verify the feasibility of control scheme, simulation and experiment are carried out.
