Model based predictive control for three-phase grid connected converter

Abstract

Model based Predictive Control (MPC) is an efficient control technique for the control of power converters. It has several advantages for this kind of controls, such as robustness to parameters variations and fast dynamic responses. The MPC considers the model of the converter-based system to forecast possible future behavior of the controlled variable. It allows selecting the optimal voltage vector to be applied so that a predefined cost function is minimized. This paper focuses on an MPC algorithm for three-phase grid connected converter. Several simulation results (under Matlab-Simulink software environment tool) and experimental results (under developed prototyping platform) are presented in order to show the effectiveness of the considered control strategy.
