Abstract :
In this paper, the mathematical model of induction motor based on rotor indirect field orientation in synchronous frame is introduced. Based on this, the current controller and the speed controller are designed in the indirect field-oriented space vector control system. The parameter is adjusted using the engineering design method and the three-phase asynchronous motor is controlled using SVPWM control strategy. The control system is simulated by MATLAB. The simulation results show that the proposed scheme is feasible and the space vector control system has a good dynamic respond.
