Abstract: In terms of the control strategy of Permanent Magnet Synchronous Motor(PMSM), a double closed-loop control system for electricity and speed which is based on Space Vector Pulse Width Modulation(SVPWM) is established. With the help of Altera DSP Builder, digital control system on the basis of FPGA is accomplished by providing the design method of sectors deciding, vector time, calculation of turn-on time, distribution of turn-on time, 6-channel PWM signal generation, Park transform and inverse transform, Clarke transform, and PI control method. Simulation results testify that the system has the advantages of static and dynamic characteristics. It also provides an effective method for SoC design of PMSM control system.
