摘要

A nonlinear control methodology for three phase grid connected of photovoltaic generator is presented in this paper. It consists of a PV arrays, a voltage source inverter, a grid filter and an electric grid. The controller objectives are threefold: i) ensuring the Maximum power point tracking (MPPT) in the side of PV panels, ii) guaranteeing a power factor unit in the side of the grid, iii) ensuring the global asymptotic stability of the closed loop system. On the basis of the nonlinear model of the entire system, the controller is carried out using an approach of Lyapunov. It is formally shown, using a theoretical stability analysis and simulation results that the proposed controller satisfies all the objectives.
