说明：  异步电机矢量控制仿真模型，采用间接磁场定向控制策略，电机模型没有采用matlab自带电机，而是根据两相旋转坐标系下的电机方程自己搭建了一个电机模型。
(Induction motor vector control simulation model, using the indirect field oriented control strategy, the motor model comes with no motor using matlab, but according to the two-phase rotating coordinate system of the motor equations built himself a motor model.)
