摘　　要：为了实现对Buck变换器直流输出电压的精确控制,优化变换器的性能,提出了一种基于双滑模面控制的控制策略,建立了数学模型,并推导了变换器滑模面的存在条件。通过仿真实验表明,采用双滑模面控制滑模变结构控制的Buck变换器具有滑模控制快速响应、鲁棒性强等特点。In order to realize the control of DC output for the Buck converter, the control method based on double sliding mode surface variable structure control is introduced in this paper. The mathematic model of the Buck converter is established, and the existence condition of the sliding mode surface is expounded. The simulation experiments shown that the Buck converter based on double sliding mode surface variable structure control have the character of good dynamic response, high robustness, and so on.
