Torque Ripple Minimizations in Switched Reluctance Motor Drives using Combined Profile Current & Torque Sharing Function

In the recent years, the use of switched reluctance motors (SRM) in industrial applications increased. These motors not only have simple and robust structure but also production cost is low. In addition these motors have some advantage like greet power, control-ability and high efficiency. However a main disadvantage of this motor is decrease torque production mechanism and saturation in their core that causes the high torque ripple and acoustic noises. Approximately more researcher utilizing linear model for SRM and focused on torque ripple minimization in commutation region but this paper utilized nonlinear model. It is clear that torque ripple is obvious in normally region in addition commutation region. For solve this problem we use current profile control and combined with TSF in order to minimizing the torque ripple. Obtained result from the simulation a three phase, 4/6 configuration SRM and compared with conventional methods, indicates validity and effectiveness of the proposed method.
