An asynchronous motor variable frequency speed regulation system based on direct torque control is established in this paper. The system uses two hysteresis controllers to compare the difference between the stator flux and the actual magnetic chain, the given torque and the actual torque respectively. Then the voltage vector applied to the stator winding of the asynchronous motor is obtained by the two difference values, and then the pulse width modulation (Pulse Width Modulation) is used. PWM) the inverter controls the asynchronous motor. According to the characteristics of the asynchronous motor direct torque control variable frequency speed control system driven by the PWM inverter, the Matlab\Simulink is used to model and simulate the variable frequency speed control system of asynchronous motor
