Improved DTC of Induction Motor with Fuzzy Controller

Abstract

DTC, also known as Direct Torque Control, is a technique employed in variable frequency drives for regulating the torque and speed of three-phase AC electric motors. This method entails determining an approximation of the motor’s magnetic flux and torque by analyzing the voltage and current readings of the motor. In order to reduce flux ripples and ensure smooth speed operation, we have suggested the use of two fuzzy logic controllers based on DTC for induction motors. The proposed method offers a faster response compared to conventional DTC for induction motors. The MATLAB simulink software was used to illustrate the comprehensive results.
