Abstract

To improve the current and torque regulation performance of the traditional deadbeat predictive current control (DPCC) for switched reluctance motors under model parameter mismatch, this article proposes an improved DPCC method based on the sliding mode strategy. First, a dedicated torque-current converter is formulated to achieve precise transformation of electromagnetic torque into corresponding q-axis current references. Second, a unified anti-disturbance sliding mode control compensation scheme is introduced into both the torque-current converter and the deadbeat controller to mitigate the negative effects of model parameter mismatch on current and torque control. This integration achieves indirect torque control through phase current modulation, effectively reducing torque ripple. Furthermore, the stability of the controller under model parameter mismatch conditions is rigorously demonstrated through Lyapunov stability analysis. Finally, the effectiveness of the proposed control method is demonstrated through simulation results, and its significant superiority in current control performance and torque ripple suppression is shown.
