Abstract

MPC techniques applied in power electronics have been categorized into two fundamental approaches: Continuous Model Predictive Control (CSS - MPC) and Finite State Model Predictive Control (FCS - MPC). The approach that FCS-MPC seeks is to use the power converter's finite number of switching states to solve the optimization problem. One of the advantages that predictive control provides is to include the nonlinearities of the converter and thus obtain the behavior of the variables for different switching states, but, on the contrary, its greatest disadvantage, and one of those that is most regularly sought to be solved, is its high switching frequency. In this work, a three-phase VSI is studied and controlled through FCS-MPC, considering its advantages and attacking its disadvantages. In this way, the switching frequency is reduced in a steady state, but in a transient state, the FCS - MPC is left in its natural state, obtaining greater power converter efficiency.
