摘要：
To effectively solve the problem of stable control of DC bus voltage in the independent photovoltaic energy storage system under multi-source disturbances, a bidirectional DC-DC converter control scheme based on enhanced linear active disturbance rejection control (LADRC) is proposed. Based on the linearized small signal model of the bidirectional DC-DC converter, an extended state observer with total disturbance differentiation is designed. Frequency domain characteristics analysis and simulation results demonstrate that the new control strategy can effectively improve the DC bus voltage tracking performance and disturbance rejection capability, and reduce the DC bus voltage fluctuation range under the condition of multi -source disturbances.
