摘　　要：为了提高光伏储能系统的快速性和抗干扰能力,同时考虑到双向变换器的非线性特性,在建立双向DC-DC变换器数学模型的基础上,提出一种基于自抗扰控制器（active disturbance rejection control,ADRC）的双向DC-DC变换器控制方法,设计适用于光伏储能双向DC-DC变换器的自抗扰控制器,并对系统进行实验验证。实验结果表明基于ADRC的控制策略能有效抑制直流母线电压波动和冲击,提高光伏储能系统的动态性能和抗干扰能力。In order to improve the system rapidity and capacity of resisting disturbance,taking into account thenonlinear characteristics of the DC-DC converters,a nonlinear control method based on active disturbance rejectioncontrol（ADRC）for the bidirectional DC-DC converter is proposed in this paper. Through analysis on working state of thecircuit,the mathematical model of the bidirectional DC-DC converter is established. The ADRC controller for thebidirectional DC-DC converter of the solar energy storage system is designed. Experimental verification of the system iscarried out,and the experimental results show that the solar energy storage system based on the ADRC can suppressfluctuations of the DC bus voltage effectively,and the proposed control method can improve the dynamic performanceand the capacity of resisting disturbance in the solar energy storage system.
