摘要：
In this paper, a sliding surface is defined based on the inductor current to construct a robust controller for Maximum Power Point Tracking (MPPT) in the photovoltaic (PV) systems. An adaptive incremental conductance algorithm has been used to obtain the set point of the controller. An improvement is achieved by this combination, especially in fast irradiance variations. The robust stability of the method is proved using the Lyapunov stability theorem. A comparative study is also made to highlight the benefits of the proposed algorithm. The features of this controller, in terms of robustness against the irradiance variations, are demonstrated by theoretical analysis, simulations and an experimental study. The results demonstrate that the proposed controller can be implemented effectively and economically with high MPPT efficiency.
