Torque ripple reduction of a switched reluctance motor including mutual inductances

Switched reluctance motor (SRM) drives offer the advantages of simple and robust motor construction, high speeds, high overall efficiencies over a wide operating range of torque and speed, simple power converter circuits with a reduced number of switches and excellent controllability. However, the SRM also has a drawback in that it generates acoustic noise. This study aims to minimize the torque ripple of an SRM in the linear region and in the presence of mutual inductances. The proposed technique is based on the control of the sum of the square of the phase currents. The proposed control technique has been applied to an SRM and successful results have been obtained. A mathematical model of a 8/6 SRM, simulation results and the proposed method are all presented in this paper.
