Simulation of hysteresis current PWM variable speed system based on Saber

对异步电动机矢量控制的变频调速系统进行了研究,使用仿真软件Saber为速度、磁链双闭环的电流滞环型PWM矢量控制系统建立了仿真模型,最后给出了仿真结果,通过仿真结果的分析从理论上证明了这个系统具有良好的动、静态特性。

The vector-control variable speed system of the asynchronous motor was studied. The simulation model of vector-control system of speed and magnetic double close-loops based on current hysteresis PWM inverter was established by using simulation software Saber and the simulation result was obtained. The simulation model was theoretically proved to have better static and dynamic performance.
