Performance Analysis of FCS-MPC Using the Generalized Formulation and Euler Method on SBBMLI

Abstract

This research addresses two finite control set-model predictive control (FCS-MPC) methods employed on the switched-battery boost-multilevel inverter (SBBMLI). The simulation analysis begins with the generalized formulation and follows with the Euler method of the FCS-MPC. The performance of the generalized formulation is considered at the capacitor connected in parallel with the load. Meanwhile, the Euler method is considered at the actual load of different configurations. A simulation analysis of a switched-battery boost-multilevel inverter (SBBMLI) is therefore designed and analyzed to demonstrate the efficacy of the proposed approach. The FCS-MPC control module with the two methods is implemented to confirm the performance of their operation using Matlab Simulink simulation. For the stated case study, a 0.21% to 1.25% increment of THD in the generalized SBBMLI problem formulation compared with the FCS-MPC using the Euler method and the tracking problem is an acceptable limit for the FCS-MPC performance deterioration.
