Study on space vector PWM technology of PMSM control system based on dSPACE

On the basis of deep study on space vector PWM (SVPWM) technology, the simulation of permanent magnet synchronous motor (PMSM) closed-loop control system based on SVPWM technology is achieved by Simulink in this paper. The simulation results show that the PMSM control system has lower torque ripples, better speed tracking and strong robust to the load interferences, which is more suitable for high-performance PMSM variable speed control system. Finally, the hardware in loop (HIL) experiments of PMSM speed and current dual closed-loop control system based on SVPWM technology is completed by dSPACE experiment platform to further verify the effectiveness of the analysis results.
