A MC56F8357 Based Permanent Magnet Synchronous Motor (PMSM) Servo System

A digital servo system based on MC56F8357 is presented in this paper. The system principle, hardware and software architectures of the AC servo drives are introduced. By utilizing field oriented control (FOC), space vector PWM (SVPWM), DC bus ripple compensation, digital PI regulating with correction of the integral term and anti-hunt processing control strategies, the hardware and software of the servo system are implemented. Experiments including different position and speed control have been carried out and the experimental results are also given
