DIRECT TORQUE CONTROLLER OF INDUCTION MOTOR

    Advanced control of electrical machines requires independent control of magnetic flux and torque. Induction motors are currently used in many industrial applications. Thus, their control techniques have received a lot of interest. An efficient method of induction motor control is direct torque control (DTC). The Direct Torque Control (DTC) method is characterized by its simple implementation and a fast-dynamic response. The main advantages of DTC are the absence of coordinate transformation and current regulator absence of separate voltage modulation block. In this design, a DTC model has been developed and tested using a MATLAB/SIMULINK as shown in the simulation video demo. The results verified based on the stator flux and torque.
