Abstract

Induction Motors have the wide range of applications due to their advantages like rugged construction, low cost and robust performance. The speed control of induction motor is essential in industrial applications. The Direct Torque Control is the well efficient method for speed control of industrial machines. Direct Torque Control is used to minimize electromagnetic torque and flux ripples. The major problems connected with DTC drives are switching frequency that varies with operating conditions and high torque and flux ripples. In order to improve the performance of the classical DTC, a new modified DTC with the fuzzy logic controller (FLC) is proposed in this paper. The use of FLC is to improve the decoupled control between flux and torque. The paper focused on the Fuzzy Logic Direct Torque Controller (FLDTC) to expand the dynamic performance compared to the classical DTC system. Finally, the results are shown that Fuzzy Logic Direct Torque Controller shows the better performance compared with the PI controllers. Results include simulation in the environment of MATLAB/Simulink.
