混合网络攻击下基于边的动态事件触发多智能体系统一致性OA

In this article,the secure consensus problem is investigated for linear multi-agent systems under an undirected topology and hybrid cyber-attacks.Firstly,a novel mathematical model is established to characterize a hybrid cyber-attacks consisting of deni-al-of-service(DoS)attacks and false data injection(FDI)attacks that occur on each edge.In order to reduce the occupation of net-work bandwidth load and save communication resources,an edge-based dynamic event-triggered mechanism is developed.Second-ly,the prediction estimators of its neighbors are designed for each agent to match the asynchronous information generated by the edge-based dynamic event-triggered mechanism.Then,a distributed consensus control protocol is proposed for multi-agent systems under the hybrid cyber-attacks by using the proposed prediction estimators and edge-based dynamic event-triggered mechanism.Fur-thermore,a sufficient criteria is derived to ensure the mean square consensus of multi-agent systems by using Lyapunov stability the-ory.Finally,the usefulness of the theoretic results presented is demonstrated via a numerical example.
