Tracking Power Photovoltaic System with Robust Polynomial Output Feedback Control Strategy
Résumé
This paper proposes a new robust stabilization conditions for Maximum Power Point Tracking (MPPT) control of photovoltaic (PV) systems based on polynomial fuzzy systems. In this scheme, an output feedback controller is exploited to reduce the number of needed sensors. The stabilization conditions are formulated in terms of sum-of-squares (SOS) conditions, which can be solved efficiently by using semidefinite program-ming (SDP) tool. The efficiency of the proposed controller is demonstrated through the simulation results.
