This article describes a technique that allows a photovoltaic (PV) production\nunit to obtain the maximum power at all times. Here, we use the MPPT control\nvia fuzzy logic on a DC/DC boost-type converter. In order to achieve our\ngoals, we first proceeded to model a PV panel. The resulting model offers the\npossibility to better account for the influence of different physical quantities\nsuch as temperature, irradiation, series resistance, shunt resistance and diode\nsaturation current. Thus, the maximum power to be provided by the PV system\nis acquired by fuzzification and defuzzification of the input and output\nvariables of the converter. Subsequently, a virtual model of an 800 Watt PV\nprototype is implemented in the Matlab environment. The simulation results\nobtained and presented, show the feasibility and efficiency of the proposed\ntechnology. Indeed, for a disturbance caused by a variation in brightness, our\nsystem guarantees the maximum stable power after 1.4 s. While for a load\nvariation, the maximum power is continuous.
