Finite Control Set MPC versus multi-loop PR control for a three-phase four-leg inverter as grid disturbances generator: a Comparative Analysis

Abstract

This study presents a comparative study between the Finite Control Set Model Predictive Control (FCS-MPC) and the multi-loop control strategy based on Proportional Resonant (PR) Controller for a three-phase four-leg inverter to generate various grid disturbances under various load conditions. It is shown that MPC has better transient response in all cases of grid disturbances. Regarding the steady-state performances, the output voltage has a lower THD when using MPC, especially for inductive loads, while the relative error on the output voltage is relatively the same for both control schemes.
