Abstract
This study presents the principle of the MPPT command. The command techniques most used in MPPT control are reviewed and analyzed such as: Observation and Perturbation (O & P) and Conductance Incrementing (CI). The aim of this study is the association of the Fuzzy Logic command with the MPPT command, then analyzing and comparing its behavior with other techniques (O & P and CI) used in the control of photovoltaic systems.
