Robust control of the Photovoltaic system with improved maximum power point tracking

A robust voltage control intended for a photovoltaic system is considered. An improved maximum power points tracking (MPPT) is presented without Photovoltaic array characteristics known. In order to cope with large parameter variations and load disturbances, second order sliding mode controller, based on super twisting algorithm for DC-DC Boost converter is proposed. The designed control shows fast MPPT and good robustness with respect to parameter variations, measurement errors and unmodeled dynamics. The experimental results confirm the effectiveness of the proposed control.
