Abstract :
In this paper, the mathematical model of induction motor based on rotor field orientation in synchronous frame is introduced. Based on this, the decoupling of stator voltage is implemented using the feed forward decoupling currentfeed forward decoupling current controller. The problem in the accuracy of flux estimation is settled using voltage model and current model flux mixing observer. Torque regulator and speed regulator are designed to ensure the precise of current amplitude, phase tracking and accurate control of speed through dual closed-loop control of current and speed loop. The SVPWM control strategy is applied to control induction motor. The simulation results show that the proposed scheme is feasible and the space vector control system has a fast dynamic respond.
