A Detailed Procedure to Implement Model Predictive Control for the Single-Phase Voltage-Source Inverter

Abstract

This study aims to provide a detailed procedure to deploy model predictive control for the single-phase voltage-source inverter. Simulation and implementation of other control methods for the single-phase voltage-source inverter, including the sinusoidal pulse width (SPWM) and the hysteresis methods, are also given. In MPC control deployment for the single-phase voltage-source inverter, the mathematical model of the inverter is first required. Based on the obtained model of the inverter, the inductor current and the capacitor voltage can be conveniently formulated. The optimal control action in each sampling period is selected based on the minimum value of a cost function. Compared to conventional control methods for the single-phase inverter, the MPC method requires accurate sensors, and its implementation is also sometimes challenging. Due to this reason, this study provides detailed steps to conveniently implement the MPC method for the single-phase voltage-source inverter. In this study, control methods for the single-phase voltage-source inverter are conveniently deployed using the KIT STM32F407 DISCOVERY. The simulation and experimental results have proven that the MPC algorithm is suitable for fully understanding the concept of model-based discrete control of the single-phase voltage-source inverter and other types of power converters.
