摘要：

The present work investigates a real time implementation of a photovoltaic grid connected chain, based on fuzzy logic MPPT controller (FLC). The implementation is realized on a dSPACE 1104 single board, controlling a boost chopper in the PV array side and a VSI inverter in the grid side. The FLC tracks permanently the maximum power point of the PV array without any prior information on the system model. The DC-link voltage controller is based on Lyapounov stability theory ensuring best performance for both transient and steady state, whereas, the hysteresis current controllers of the inverter allow a quasi-total transit of the maximum extracted PV power to the grid under unity power factor operation. The obtained results via Matlab-Simulink simulation are confirmed through experiment proving the effectiveness of the used control method.
