Abstract

To address the inherent drawbacks of large torque ripple and severe vibration and acoustic noise in switched reluctance motors (SRMs) for electric vehicle applications

this paper designs a dynamic voltage regulation converter and proposes an model prediction compensation torque sharing function (MPC-TSF) control strategy. First

the operating mechanism of the dynamic voltage regulation converter is analyzed. The converter features six operating modes

enabling flexible regulation of the motor excitation and demagnetization processes. Furthermore

the fundamental principle of the MPC-TSF strategy is illustrated. By predicting the electromagnetic torque and optimizing the phase voltage output in real time

the proposed method achieves optimal torque ripple suppression. Finally

experimental verification is carried out on a 12/8-pole SRM prototype. The results show that

compared with traditional control schemes

the proposed method can effectively suppress SRM torque ripple while significantly improving the motor's torque output capability.
