Enhanced Performance of Three-Phase Squirrel-Cage Induction Machine Drive System using Model-predictive-controller in MATLAB/SIMULINK environment

Abstract

From decades, the three-phase squirrel-cage induction motors are widely being used as industrial drives as they are self-starting, rugged, reliable, and economical, but its precise torque control is still a challenge. Therefore, this work presents a systematic design procedure to develop the novel control strategy, i.e., the model predictive controller for an induction machine drive system using an input-output linearized model of this machine. The results of the proposed scheme are compared with the conventional Proportional Integral (P-I) controller-based system, showing the superior performance of the model predictive controller using MATLAB/SIMULINK environment. The parameters of P-I controller have been calculated using Zeigler Nicholas (ZN) method.
