Steady-state issues with finite control set model predictive control

Finite Control Set Model Predictive Control (FCS-MPC) is a novel and promising control scheme for power converters and drives. Many practical and theoretical issues have been presented in the literature, showing good performance of this technique. The present work deals with one of the most relevant aspects of any controller, namely, the steady-state operation. As will be shown, basic FCS-MPC formulations can be enhanced to achieve a zero average steady-state error. We focus on a simple H-Bridge power converter with two complementary switches and discuss benefits and drawbacks of our proposal.
