摘　　要：根据状态方程,利用SIMULINK软件构建了异步电动机的动态结构及坐标变换结构,采用自然采样方法仿真调制电路,构成SPWM调速系统.通过加载,变载及变压变频直接观测电动机的转速、磁链、定子电流的动态变化及电动机的机械特性.系统模拟真实系统,对理论教学起到有效的辅助作用.It is based on the dynamic models of asynchronous electromotor and the coordinate transformation and Natural sampling theory that we have achieved the simulation of the SPWM control models by using Simulink software package.It can be directly observed that the changing of speed and magnetic and electromagnetic and current and mechanical characteristic by loading and Variable Voltage and Variable Frequency.The system can simulate the real system.It is conducive to theory teaching.
