Abstract

This work aims at designing a Maximum Power Point Tracking (MPPT) controller to optimize the photovoltaic (PV) produced power. For each pair of temperature and solar irradiance, there is a single operating point corresponding to the maximum power delivered to the load. As being a nonlinear system, the photovoltaic (PV) system can be described by Takagi Sugeno (T-S) fuzzy model. The proposed MPPT control scheme which allows the maximum power transferring from the PV panel to the load is mainly based on Parallel Distributed Compensation (PDC) technique. The control gains have been computed based on Linear Matrix Inequalities tools (LMI). Lyapunov approach has been applied to prove the stability of the system. The performance of the proposed controller is exhibited by simulation results.
