Abstract：Because the energy density and conversion efficiency of photovoltaic cells are relatively low,and its output power is greatly affected by the light intensity and ambient temperature,it is necessary to dynamically adjust the output power to ensure the optimal power output of photovoltaic cells.According to the application characteristics of photovoltaic cells,ADRC technology is proposed,and a maximum power point tracking(MPPT)controller based on first-order ADRC technology is designed to quickly determine the optimal output power of photovoltaic cells,shorten the system adjustment time and improve the tracking rate.In order to verify the tracking effect of the designed active disturbance rejection controller,a mathematical model of photovoltaic cell charging was constructed and verified by Matlab/Simulink.The results show that MPPT controller with first order active disturbance rejection control can track the maximum power point quickly and accurately.
