Abstract: This paper discusses the reduction of torque ripple in a 6/4 switched reluctance motor using turn-on and turn-off controllers, and compares the results with those obtained using conventional controllers. Torque ripple is a common problem in switched reluctance motors, which leads to vibration, noise, and reduced efficiency. The turn-on and turn-off controllers proposed in this study aim to improve torque control and reduce ripple by adjusting the current waveform. The study presents simulation results, which demonstrates the effectiveness of the new controllers in reducing torque ripple and improving the motor's performance compared to traditional controllers. Additionally, the impact of adding a resistor to the de-energised return path in the asymmetric converter for each phase is fully explored. The proposed approach may have significant implications for the design and operation of switched reluctance motors in various applications.

Keywords: torque ripple; reduction; 6/4 switched reluctance motor; turn-on; turn-off; current waveform; de-energised return path; asymmetric converter; double-salient; speed response; MATLAB\Simulink.
