Decoupling control of induction motor based on differential geometry theory

The induction motor is a major portion of the alternating current speed system and the decoupling control of the induction motor is major problems bringing about excellent performance of the system. The decoupling control problems of the induction motor were dealt with 5-order nonlinear model of the motor was converted to the affine nonlinear system form. Then, based on the differential geometry theory of nonlinear systems, the coordinate transformation was performed for the new model, in which the systems were decomposed to two separate subsystems using nonlinear decoupling methods. Consequently, rotor speed and rotor flux of the induction motor are decoupled dynamically. The simulation results show that the proposed method has fine control performance.
