This paper presents a modified version of the direct torque control (DTC) in order to improve the performance of the induction motor (IM) operation. The main goal is to reduce the high ripples that constitute the major drawbacks, and which lead to an acoustical noise and degrade the performance of the control scheme, especially at low-speed regions. The augmentation of the number of sectors is a very useful solution, the modified DTC provides a constant switching voltage frequency. This technique reduces the high ripples level in the torque and the flux in spite of its complexity. The twelve sectors DTC with a modified switching table is an effective solution. The obtained results are satisfactory and the performance of the proposed strategy is improved. The results of all the discussed aspects have been obtained by numerical simulation using MATLAB/Simulink.
