Fuzzy Logic Control for the tracking of maximum power point of a PV system

Tracking of the maximum power point (MPPT) plays an important role in photovoltaic (PV) power systems because they maximize the power output from a PV system for a given set of conditions, and therefore maximize they array efficiency. This work presents a comparative study between different control strategies used most conventional digital namely perturbation and observation (P & O) and incremental Conductance (INC) with digital control by fuzzy logic (FLC). The introduction of fuzzy controller as a solution has given very good performance and whatever the parametric variation of the system.
