摘　　要：针对dSPACE4002的8路PWM输出端口,设计了一种实现SPWM的方法。将设计的SPWM算法通过dSPACE的RTI(实时接口)下载到实时硬件中,借助dSPACE系统提供的Con-trolDesk环境对实验过程进行实时观测,从而实现对永磁同步电机的实时控制。针对永磁同步电机起动问题,设计了一种在起动时刻变频加速的软起动方法,得到了实验验证。A new method for SPWM implementation is proposed, based on the PWM output of dSPACE. The SPWM control algorithm is downloaded to the real-time hardware to control the permanent magnetic synchronous motor on the basis of dSPACE platform. The result shows the feasibility of the design of SPWM. Further more, the article designs a variable frequency SPWM to resolve the problem that synchronous motor is difficult to start. The experiment result verifies the validity of algorithm.
