Abstract:

The control system of induction motor used in electric vehicle was designed, and the feed-forward decoupling vector control strategy was adopted. Rotor flux orientation correction strategy was proposed based on q-axis component of rotor flux, improving the torque control accuracy and dynamic response. Then, the hardware units and software units of torque controller of induction motor were achieved. The torque control strategy was tested and demonstrated by the simulation and experiments.

Key words: electric vehicle, induction motor, vector control, feed-forward decoupling
