The AC motor is an important mechanism of energy converting between mechanical and electrical. It has stronger electro-magnet couple. One of the deviation de-couple control method of induction motor is proposed which based on the AC motor rotor field-oriented control and applied non-vary principle of control theory. The mathematical calculations process of above method is given. The robust of above method is analyzed. The vector system structure and de-couple schemes, affecting de-couple factor are studied. The different de-couple methods has been compared by computer simulation. The feasibility of above scheme is verified by physical experiment. The result of de-couple controlling are showed by theory analysis and experiment.
