摘要
为提高混合储能系统及直流微电网的鲁棒性,建立带有扰动上界未知的DC/DC状态空间平均模型,采用反演控制和变结构控制相结合的方法,提出反演自适应变结构控制。在Matlab/Simulink中搭建独立型直流微电网的仿真模型,仿真结果表明,相对于PI控制,反演自适应变结构控制有效抑制了负载突变时直流微电网的母线超调电压,缩短了电压稳定时间,提升了混合储能系统及直流微电网的鲁棒性。
For improving robustness of hybrid energy storage system and DC micro grid,the back stepping adaptive variable structure control is proposed by combining back stepping control and variable structure control the basis of DC/DC state space averaging model with unknown upper bound. The simulation model of independent DC micro grid is set up in Matlab/Simulink. It is shown by the simulation result that the back stepping adaptive variable structure control can,compared with PI control, effectively suppress the overvoltage of the bus of DC micro grid in the sudden change of load,shorten voltage stability timeand im prove robustness of the hybrid energy storage system and of DC micro grid.
