| Abstract: | 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. |
