Abstract

This paper presents an investigation of the dynamic performance of Fuzzy Logic Control based on conventional Direct Torque Control (FLC-DTC) to mitigate torque ripples with a three phase Induction Motor (IM). This combination of FLC and DTC limits the level of torque ripple and improves the work performance of the IM. The IM is mainly used in industrial applications because of its advantages related to size limit and self-starting performance compared to other motors. The dynamic behaviour of IM is investigated in terms of parameters such as torque, speed, and flux. In the proposed work, a fuzzy logic control (FLC) with the trapezoidal and triangle membership functions (MFs) is used to produce an optimal control pulse signal, which controls the speed of the IM. Based on the parameters of MFs, the motor speed is dynamically controlled, and the quantity of torque ripples is minimized. Furthermore, FLC-DTC selects the appropriate inverter Voltage Vector (VV) by analysing three input variables: torque, flux, and flux angle to select the best VV using FLC rules. The implementation result indicates that the proposed control reduces the torque ripples twofold compared to the DTC. The proposed control method is implemented in MATLAB/Simulink platform, and the performance analysis highlights the efficiency of the suggested approach.
