Research of Direct Torque Control of Asynchronous Motor

Direct torque control (DTC) as a new type of motor control strategy, make the control system has good dynamic regulation performance. In this paper, we use the theory of direct torque control to research the speed regulation system of asynchronous motor direct torque control principle and its main component. Use Matlab/Simulink library to build the simulation model of induction motor DTC complete simulation and results show that the direct torque control run time has good control effect in asynchronous motor.
