DoS攻击下CPS容错控制与通讯协同设计

Co-design of Fault-tolerant Control and Communicantion for Cyber Physical System under DoS Attack

针对遭受拒绝服务(Denial-of-Service,DoS)攻击的信息物理系统(Cyber Physical System,CPS),研究了其基于离散事件触发通讯机制(Discrete Event-triggered Communication Scheme,DETCS)的容错控制与通讯协同设计问题。首先,为减少信息传递过程中通讯资源的浪费,引入DETCS,使网络带宽得到充分利用;接着,建立具有非均匀传输的CPS闭环模型,进而给出了DoS攻击下的CPS具有鲁棒和网络通讯协同设计的方法;最后,通过仿真算例验证了该方法的有效性。

Aimed at Cyber Physical System(CPS)with Denial-of-Service(DoS)attack,this paper studies the co-design of fault-tolerant control and communication based on Discrete Event-triggered Communication Scheme(DETCS).Firstly,in order to reduce the waste of communication resources in the process of transmission,DETCS is introduced to make full use of the network bandwidth.Then,the closed-loop model of CPS is established with the non-uniform transmission,and the co-design method of CPS with robust performance and network communication is given under DoS attack.Finally,by means of simulation example,the feasibility and effectiveness of the proposed method is verified.
