Abstract: A direct torque control system of induction motor was constructed with Matlab/Simulink based on the mathematic module of induction motor. Through the experiment emulated by the Matlab, the waveform of stator voltage, stator current, rotor speed, electromagnetic torque and stator flux were given. The simulation results comfirmed this control method had higher dynamic response and comparatively stronger robustness.
