Smooth Speed Control for Low-Speed High-Torque Permanent-Magnet Synchronous Motor Using Proportional–Integral–Resonant Controller

This paper proposes a speed and current proportional-integral-resonant (PIR) control strategy to realize smooth speed control of the low-speed high-torque permanent-magnet synchronous motor (PMSM) drive system by minimizing the periodic torque ripples. Some nonideal factors causing periodic torque r... View More
