    Abstract: In order to carry out the maximum power point tracking (MPPT) control and improve the output efficiency of solar battery, this paper used the sliding mode control in the photovoltaic system for MPPT control and designed the sliding mode controller based on photovoltaic MPPT control. The solar battery model was established, as well as the Boost converter and the sliding mode MPPT control model, and they were carried out simulation in MATLAB. The results show that the sliding mode MPPT control can quickly realize the MPPT for photovoltaic systems, shorten the adjustment time, and reduce the overshoot and steady-state errors.
    Key words: photovoltaic generation; Boost converter; sliding mode control; maximum power point tracking
