This article concentrates on event-based secure leader-following consensus control for multiagent systems (MASs) with multiple cyber attacks, which contain replay attacks and denial-of-service (DoS) attacks. A new multiple cyber-attacks model is first built by considering replay attacks and DoS attacks simultaneously. Different from the existing researches on MASs with a fixed topological graph, the changes of communication topologies caused by DoS attacks are considered for MASs. Besides, an event-triggered mechanism is adopted for mitigating a load of network bandwidth by scheduling the transmission of sampled data. Then, an event-based consensus control protocol is first developed for MASs subjected to multiple cyber attacks. In view of this, by using the Lyapunov stability theory, sufficient conditions are obtained to ensure the mean-square exponential consensus of MASs. Furthermore, the event-based controller gain is derived by solving a set of linear matrix inequalities. Finally, an example is simulated for confirming the effectiveness of the theoretical results.
本文专注于具有多种网络攻击（包括重放攻击和拒绝服务（DoS）攻击）的多智能体系统（MAS）基于事件的安全领导者跟随一致性控制。首先通过同时考虑重放攻击和DoS攻击构建了一种新的多网络攻击模型。与现有关于具有固定拓扑图的MAS的研究不同，本文考虑了DoS攻击导致的MAS通信拓扑变化。此外，采用事件触发机制通过调度采样数据的传输来减轻网络带宽负载。然后，首先为遭受多种网络攻击的MAS开发了一种基于事件的一致性控制协议。鉴于此，利用李雅普诺夫稳定性理论，获得了确保MAS均方指数一致性的充分条件。此外，通过求解一组线性矩阵不等式得出基于事件的控制器增益。最后，通过一个例子进行仿真以验证理论结果的有效性。
