A Novel Duty Ratio Interval Subdivision Based MPTC Method for PMSM

This paper presents a novel model predictive torque control(MPTC) method to enhance the control accuracy and performance of three-phase permanent magnet synchronous motors (PMSM). Based on the duty ratio control method, this novel method divides the action stages of the control vectors more accurately. This precise division allows for more effective suppression of torque ripple, which is a common challenge in PMSM control. Through simulations, the results confirm that this innovative method effectively reduces torque ripple and shortens system response time, improving both dynamic and steady-state performance. These improvements contribute to enhancing the overall performance of the PMSM, making it more responsive and robust in various operating conditions.
