摘　　要：针对永磁同步电动机的起动过程,利用dSPACE实时仿真平台建立了一种通用的变频SPWM控制结构模型。介绍了该SPWM控制模型的软、硬件构成。通过dSPACE系统与外围驱动电路对三相永磁同步电动机的起动过程进行了实时仿真。实验结果表明设计的SPWM控制算法具有一定的可行性。Based on dSPACE system, a kind of general vary-frequency sine wave PWM （SPWM） control 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.
