MPPT control method of PV system based on active disturbance rejection control

摘要

This paper presents a maximum power point tracking method based on the active disturbance rejection controller. The tracking-differentiator is used to obtain the differential signal of current and voltage, and the system is controlled by the active disturbance rejection controller to ensure the system works at the maximum power point. The proposed strategy is validated in Matlab/Simulink, and the feasibility and superiority of the algorithm are verified by comparing with the traditional incremental conductance method based on PI controller.
