Abstract

In order to minimize torque ripple in a switched reluctance motor (SRM), various control methods have been proposed. One such method is current profiling control based on a mathematical motor model concerned with the relationship between torque position and current, which can be derived from measured magnetizing curves. However, current profiling control faces issues with an increase in torque ripple at the current overlapping region depending on the load condition. In this study, through magnetic analysis using 2D-FEA and mathematical analysis based on a test SRM (four-phase, 400W, and 8/6 pole configuration), the reason why the torque ripple increases is revealed, and a modified torque-position-current model considering mutual coupling is proposed for better control of torque ripple minimization. Experimental studies on torque ripple minimization using the test motor show that the proposed current profiling control offers better torque ripple control performance.
