摘　　要：针对双闭环控制策略在双向DC/DC变换器动态性能、谐波抑制和抗干扰能力等方面不足,提出一种鲁棒反演滑模控制策略,建立锂离子电池等效电路模型,搭建双重化双向DC/DC变换器主电路,最终利用实验平台对锂离子电池组在两种控制策略下充放电情况进行对比分析,同时对鲁棒反演滑模控制策略下输入电压大幅扰动进行研究。实验和仿真验证所提方法有效性,在锂离子电池组充放电控制上鲁棒反演滑模控制策略相对双闭环控制策略更具有优势且对提高蓄电池充放电效率具有普遍性。Considering the disadvantages of the traditional double loop control strategy in dynamic performance,harmonic suppression and anti-interference ability,robust backstepping sliding move control strategy is proposed. Equivalent circuit model of lithium ion battery was established,the main circuit of double-channel interleaved bi-directional DC/DC converter was built. Finally a comparative study will be conducted on lithium ion batteries charge/discharge condition on the experiment platform by two kinds of control strategies. At the same time,the problem of input voltage disturbance is studied under the control of rubost backstepping sliding move. The effectiveness of the proposed method is verified by experiments and simulations. the experiment will verify that robust backstepping sliding move control strategy has much more advantages than double closed-loop control strategy in the control of charging and discharging for lithium ion batteries and the control strategy is universal for improving the charging and discharging efficiency of the battery.
