Comparison of Model Predictive Control Strategies for Voltage Source Inverter with Output LC Filter

Abstract

This paper proposes a comparison between three model predictive control strategies Optimal Switching Vector (OSV-MPC), Modulated Model predictive Control (M2PC) and Optimal Switching Sequence (OSS-MPC). OSV-MPC is simple, intuitive to implement and has a fast transient response. However, the technique produces a variable switching frequency. M2PC and OSS-MPC are recent techniques to achieve a fixed switching frequency with the main advantages of OSV-MPC. The strategies will be presented and Matlab®/Simulink simulation comparison, in transient and steady state, will be implemented for a VSI with output LC filter.
