Vector control based on dynamic model is of high performance of ac motor drive system is one of the control scheme. The so-called vector control, is through the vector transform and according to the rotor flux, get equivalent for dc model, in the rotor flux coordinate system, with the method to control for dc electromagnetic torque and magnetic chain, then will the rotor flux of the control by the transformation of coordinates get the corresponding amount three-phase coordinate system, in order to implement the control.
