【Abstract】 Based on dSPACE system,a kind of general vary-frequency sine wave PWM(SPWM)con- trol configuration model aimed at the starting course of permanent magnet synchronous motor(PMSM) was proposed in this paper.Software and hardware structure of the vary-frequency SPWM control model was explained in details.By dSPACE system and outside driving circuit,the starting course real-time simulation of PMSM was achieved completely.The experiment results indicate that the vary-frequency SPWM control algorithm was feasible.更多还原
