Research on the system of the rotor field-oriented forward-feed decouple control for induction motor

In this paper, the asynchronous motor rotator field-orientation system which used forward-feed de-couple control method is studied, based on discussing implementation scheme which aims at high power AC motor drive control. The asynchronous motor de-couple scheme and vector control system structure, and affecting factor on the AC motor de-couple and field-orientation are analyzed. AC motor rotator resistance is distinguished and its methods compared. Vector control system scheme is tested. The experiment and theory analysis have proved the scheme is practical.
