Optimization of the Fuzzy MPPT Controller by PSO for the Single-Phase Grid-Connected Photovoltaic System Controlled by Sliding Mode

This paper focuses on the performance of a single-phase inverter coupled to the grid in terms of optimal photovoltaic transfer, using the concept of sliding-mode variable structure systems. Moreover, a fuzzy logic control technique optimized by particle swarm algorithm (PSO) associated with a boost converter is used to extract the Maximum Power Point Tracking (MPPT).The validation of the results using Matlab/Simulink software is carried under different environmental and operating conditions to verify the satisfactory performance of the proposed control strategies.
