Abstract
In this paper, the simulation of dynamic model of Linear induction Motor (LIM) using Model predictive control (MPC) is presented. Various control methods have been previously proposed for the control of three phase two level inverter. A Model Predictive Control method is a simple and powerful control scheme used for the control of voltage of a three-phase inverter. A discrete time model of the inverter, filter and the load is used by the controller to predict the behavior of the output voltage for each possible switching state. A MPC is an optimization process that uses a cost function to minimize the error between the measured output voltage and the reference voltage. Switching state of the voltage vector that gives the minimum error is selected and given to the inverter during the next sampling instant. The proposed predictive control method performance for LIM at various sampling frequencies is simulated using MATLAB/Simulink tools for Total Harmonic Distortion (THD) analysis.
