T-S implementation of an MPPT algorithm for photovoltaic conversion system using poles placement and H∞ performances

Abstract

A photovoltaic (PV) conversion system consisting of PV Panel, DC/DC boost converter and a DC (Direct Current) load, is considered in this work. This paper proposes T-S fuzzy method to deal with Maximum Power Point Tracking (MPPT) problem. The stability analysis of the closed loop system is carried out using Lyapunov method and the control gains can be designed by solving Linear Matrix Inequality (LMI). In this study, the MPPT algorithm based on fuzzy inference system (FIS) is designed to generate the maximum power voltage. In order to validate our control strategy, experimental tests are proposed. The available environment in our laboratory includes solar modules, a DC/DC boost converter and dSPACE DS1104 card with its real-time interface Control Desk.
