Abstract
A new approach to Direct torque control of induction motor is presented in this paper.A ripple in torque of the induction motor is a very common problem and it is to bereduced. In conventionalDTCmethodstheinverter has constant switching frequency and is dramatically increased. In proposed DTC based induction motor drive, an improved space vector modulation technique is applied to inverter control, therefore reducingthe torque/speed ripples. As the proposed approach does not include any dead beat control or hysteresis control, it automatically reduces computational calculations. Simulation results of proposed DTC based induction motor drive technique is validated using MATLAB/SIMULINK environment
