Abstract: To address the issue of excessive torque ripple in switched reluctance motor (SRM) ,an optimized threeinterval torque sharing function ( TSF) control strategy is proposed. The commutation torque is partitioned and optimized based on inductance characteristics, allowing full utilization of the outgoing phase ’ s torque tracking capability and the incoming phase’ s excitation ability,thereby achieving a more rational torque distribution. Simulation results based on a fourphase 8 / 6 SRM demonstrate that,under the same load conditions,the proposed method effectively suppresses torque ripple across both low-speed and high-speed operating regions compared to the conventional cubic TSF. It reduces the torque ripple
rate by approximately 10% and enhances operational efficiency.
