摘　　要：微能源网是一种典型的信息物理系统,通过稀疏网络传递控制信息,易受网络攻击,影响系统的稳定性,甚至造成系统失稳。该文将拒绝服务攻击考虑到微能源网信息物理系统(CPS)控制中,分析拒绝服务攻击机理以及攻击频率对系统的影响。并设计基于事件触发一致性算法的弹性控制器,通过Lyapunov理论证明该控制系统的稳定性,能够避免Zeno现象的发生。该控制器能够在拒绝服务攻击下实现控制目标,并具有较好的动态性能。最后,在Matlab/Simulink仿真平台验证该控制方法的可行性和有效性。Micro-energy grid is a typical cyber physical system.It transmits control information through sparse network,which is vulnerable to cyber-attacks,affects the stability of the system,and even causes system instability.This paper takes the denial-of-service attack into account in the CPS control of micro energy grid,analyzes the mechanism of denial of service attack,and the impact of attack frequency on the system.An elastic controller based on event-triggered consensus algorithm is designed.The stability of the control system is proved by Lyapunov theory,which can avoid Zeno phenomenon.This controller can achieve control objectives under denial-of-service attacks and has good dynamic performance.Finally,the feasibility and effectiveness of the proposed control method are verified on the MATLAB/Simulink simulation platform.
