An efficient Fuzzy Logic MPPT Control Approach for Solar PV System: A Comparative Analysis with the Conventional Perturb and Observe Technique

In this paper, a Fuzzy Logic control (FLC) approach is proposed to track the maximum power in photovoltaic solar systems. In order to prove the performance of the proposed maximum power point tracking (MPPT) FLC algorithm, a comparative analysis is established with the conventional Perturb and Observe (P & O) control approach. The comparative study is carried out under variations in insolation and temperature. All obtained results prove the superiority of the FLC approach in terms of oscillation dynamics and response time of the system at starting and to track the maximum power point (MPP).
