Research on Permanent Magnet Synchronous Motor Control System Based on DSP

The theory of permanent magnet synchronous motor(PMSM) rotor magnetic field-oriented vector control is analyzed,and the space vector pulse width modulation(SVPWM) is used in the design of AC PMSM control system based on DSP.This paper gives profound analysis and designs on the hardware circuit and software of the control system.The experiment results show that the control system can achieve the double closed-loop control in speed and current and voltage,so the control system has a practical value.
