This article investigates the containment control problem for multi-agent systems (MASs) that are affected by aperiodic denial-of-service attacks using event-triggered strategies (ETSs) in a directed graph. To overcome the limitation of the Luenberger observer, which requires a trade-off between rise time and overshoot, we design a reset observer with improved error convergence performance and more reasonable reset conditions to estimate the states of the MASs. To conserve communication resources, we introduce an ETS into the reset observer-based containment controller. To avoid Zeno behavior, a trigger known as the “Zeno-free trigger” is introduced, which prevents Zeno behavior by setting a fixed triggering interval as the lower bound of the event-triggered interval. Finally, the effectiveness of the designed protocol is demonstrated through a case involving a formation of unmanned air vehicles (UAVs). By comparing the reset observer with the Luenberger observer, the superior performance of the reset observer is demonstrated.

通过事件触发策略重置基于观察者的遏制协议，以实现多智能体网络抵御非周期性 DoS 攻击


本文使用有向图中的事件触发策略 （ETS） 研究了受非周期性拒绝服务攻击影响的多代理系统 （MAS） 的遏制控制问题。为了克服 Luenberger 观测器需要在上升时间和过冲之间进行权衡的局限性，我们设计了一个具有改进的误差收敛性能和更合理的重置条件的重置观测器来估计 MAS 的状态。为了节省通信资源，我们在重置基于观察者的遏制控制器中引入了 ETS。为避免 Zeno 行为，引入了一个称为“Zeno-free trigger”的触发器，它通过将固定触发间隔设置为事件触发间隔的下限来阻止 Zeno 行为。最后，通过涉及无人驾驶飞行器 （UAV） 编队的案例证明了所设计协议的有效性。通过将 reset observer 与 Luenberger observer 进行比较，证明了 reset observer 的卓越性能。
