摘　　要：针对未知虚假数据注入攻击下的直流微电网系统,提出了一种基于固定时间滑模的一致性控制方法。首先,建立含恒功率负载和储能单元的孤岛直流微电网系统数学模型,并构建虚假数据注入攻击模型;其次,构造观测器以估计未知虚假数据注入攻击信号,得到攻击下的系统模型;再次,基于一致性算法平均母线电压,通过固定时间滑模控制方法,设计固定时间滑模控制器;最后,以未知虚假数据注入攻击下的直流微电网系统进行仿真。仿真结果表明:设计的控制方法能抑制虚假数据注入攻击对系统产生的不良影响,相较于传统控制方法能使系统更具稳定性和鲁棒性。A bus voltage control for a DC micro-grid system under unknown false data injection attacks using a fixed-time sliding mode consensus control approach is investigated in this paper.First,a mathematical model of an islanded DC micro-grid system with constant power loads and energy storage units is established,and a model for simulating false data injection attacks is constructed.Next,an observer is designed to estimate the unknown false data injection signals,yielding the system model under attack conditions.Then,based on the consensus algorithm for bus voltage averaging,a fixed-time sliding mode controller is designed using the fixed-time sliding mode control method.Finally,simulation experiments on a DC micro-grid system under unknown false data injection attacks demonstrate that the proposed control method effectively suppresses the adverse effects of such attacks.Compared with traditional control methods,the proposed approach achieves stabilization within a fixed time,demonstrating superior robustness and reliability.
