Control Techniques of Torque Ripple Minimization for Induction Motor

Abstract

A Matlab-Simulink environment used to build a model of an Induction Motor (IM) to study and explore methods for minimizing the torque ripple. Various control strategies were reviewed and simulation studies were carried out for the following control methods: Direct Torque control, Direct Torque control with harmonic elimination, and Direct Torque control with Matrix convertor were the obtained results analyzed, evaluated, and compared to each other. The simulation results confirmed that Using Direct Torque Control with Harmonic elimination method was significantly minimized the torque ripple as the harmonics of the output voltage were canceled; discussions and conclusions were presented in this study.
