说明：  he energy generated using a photovoltaic (PV) are depends mainly on meteorological factors such as temperature and solar radiation. Considering the high cost and the low efficiency of a PV system, it must operate at maximum power point (MPP) which changes with the load variations and weather conditions. This article presents the conception of a nonlinear controller for the DC-DC converter to retrieve a maximum power from photovoltaic systems (PV). This is affected via the control of duty cycle of the converter. The backstepping control is used to design the controller. The incremental conductance algorithm provides the output reference voltage PV to the backstepping controller. An integral Action is added in order to render the controller robust against changes of parameters and perturbations. The proposed controller performance is assessed by numerical simulations under changing atmospheric conditions(efficiency of a PV system, it must operate at maximum power point (MPP) which changes with the load variations and weather conditions.
