PI-based direct torque control of PMSM for torque ripple reduction

This paper addresses the challenge of torque ripple in Permanent Magnet Synchronous Motors (PMSMs) through the implementation of a Proportional-Integral (PI)-based Direct Torque Control (DTC) strategy. Torque ripple, a phenomenon affecting motor performance, is mitigated by leveraging the simplicity and fast response of DTC, augmented by the precision of PI controllers. The objectives encompass a comprehensive understanding of PMSM characteristics, the design and implementation of the PI-based DTC system in MATLAB Simulink, and an in-depth analysis of its performance in torque ripple reduction. The paper also involves comparative studies with traditional control methods, parameter tuning for optimization, and assessments of versatility under varying conditions. By achieving these objectives, the research contributes to the advancement of control strategies for PMSMs, enhancing their efficiency and adaptability in industrial applications. The outcomes are documented and presented, providing valuable insights for future advancements in electric motor control.
