In order to improve the performance of hybrid energy storage system, a control strategy based on active disturbance rejection control (ADRC) was proposed. The extended state observer was used to estimate and compensate the internal and external unknown disturbances, and fuzzy adaptive was combined with the extended state observer to improve the stability and disturbance rejection of the system. Finally,
