Robust control of the Boost converter applied in photovoltaic systems using second order sliding mode

A robust voltage control intended for a photovoltaic systems is considered. The proposed controller is robust to environment changes and load variations. In this paper, the second order sliding mode controller based on super twisting algorithm for DC-DC Boost converter is proposed for increases the robustness of the global system. The designed control is simple, but it shows good stability and robustness with respect to load variations, the performance of the controller is verified through experimental results.
