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 the direct torque control (DTC). In this project, a DTC model has been developed and tested using a MATLAB/SIMULINK package. A 6 kW three phase induction motor has been used in order to run and evaluate the developed model. Simulation results have shown the validity and high accuracy of the proposed model. The independence of torque and stator flux control has been confirmed. However, further work should be done in order to limit the significant variation in the starting up stator current caused by any small variation in the stator flux in the developed DTC model.
