Observer-Based Event-Triggered Containment Control for MASs Under DoS Attacks
针对线性多智能体系统在拒绝服务攻击下状态不可测的问题，提出了一种保守性更低的分离法观测器设计方法，并基于观测器状态设计了事件触发包含控制器，能节省通信资源且消除Zeno行为。
This article studies the observer-based event-triggered containment control problem for linear multiagent systems (MASs) under denial-of-service (DoS) attacks. In order to deal with situations where MASs states are unmeasurable, an improved separation method-based observer design method with less conservativeness is proposed to estimate MASs states. To save communication resources and achieve the containment control objective, a novel observer-based event-triggered containment controller design method based on observer states is proposed for MASs under the influence of DoS attacks, which can make the MASs resilient to DoS attacks. In addition, the Zeno behavior can be eliminated effectively by introducing a positive constant into the designed event-triggered mechanism. Finally, a practical example is presented to illustrate the effectiveness of the designed observer and the event-triggered containment controller.
