Adaptive Control for a Class of Uncertain Nonlinear Systems : Application to PhotovoltaÏc Control Systems

Abstract : In this technical note, an adaptive control framework for compensation of uncertainties and perturbations that satisfy the matching condition on a class of nonlinear dynamic systems is presented. The proposed method does not need the explicit knowledge of the bound values on the uncertainties, and the resulting compensatory term is continuous. The application of this formulation for maximum power point tracking and unity power factor on grid-connected photovoltaic systems is presented.
