Model predictive control for electrical drive systems-an overview

Abstract

This paper reviews the classification and application of the model predictive control (MPC) in electrical drive systems. Main attention is drawn to the discrete form of MPC, i.e. finite control set model predictive control (FCS-MPC), which outputs directly the switching states of power converters. To show the diversity and simple realization with various control performances of the strategy, in this paper, several different FCS-MPCs with their working mechanisms are introduced. Comparison of FCS-MPC with conventional control strategies for electric drives is presented. Furthermore, extensive control issues, e.g. encoderless control and disturbance observation are also included in this work. Finally, the trend of research hot topics on MPC is discussed.
