This paper compares the feedback voltage decoupling vector control system with the feed forward voltage decoupling vector control system, The former has a simple structure, and the latter can gain high precision of control. In order to raise the precision, a feedback voltage decoupling vector control system is brought forward, a controller is designed, a model of the system is built, simulation is carried out to test the transient characters, robustness of the stator's resistance variation and the precision of control.
