在 Matlab/Simulink 中，建立独立的功能模块，如电机本体模块、矢量控制模块、速度控制模块、电流滞环控制模块等，再进行功能模块的有机整合，搭建交流异步电机控制系统的仿真模型。-In M atlab/Simulink, the independent　function al blocks,

such as　Moter modelblock,Vector control　 block, Speed controller block, and Hysteresis current　controllerblock　etc,have

been modeled.　By the organic combination of these blocks, the　model of control system　canbe establishedeasily.
