| Popis: | In this work, we use the Backstepping controller with integral option to track the maximum power point of a photovoltaic (PV) system. The controller is applied in three cases of the solar panel. In the first case the PV without resistances: series and shunt resistances, while in the second case the PV with series and shunt resistances, the third case consist of PV with constant series resistance, and therefore, shunt resistance values are changed up to plus 50%, without forgetting the variation of the weather conditions solar irradiation and temperature, to check whether the controller is rigor and robust enough. The system under study contains PV associated to a load via DC/DC Boost converter, and we have a Backstepping control design integrated the integral option added to ameliorate the strong control performance of nonlinear controller. The Backstepping strategy for getting the optimal power point and system stability is used Lyapunov's analysis. The system and the control method is analyzed with a simulation model that was based in Simulink/Matlab. |
