Realization of maximum power tracking approach for photovoltaic array systems based on T -S fuzzy method

A micro-grid power system consisting of a photovoltaic (PV) array panel, DC/DC converter, and a battery is considered in this research. This thesis proposes a T-S fuzzy method to deal with the power tracking problem of the power generating systems. Then, the stability analysis is carried out using Lyapunov direct method whereas the control problem is formulated into the feasibility of solving a set of linear matrix inequality (LMIs). To verify the performance, we focus on the experiment in hardware realization. To this end, we establish an experiment environment for the solar power system, which includes an SP75 solar module, a DC/DC buck converter, an A/D DS1103 card, and a real-time interface, dSPACE. The results show satisfactory performances for the proposed scheme.
