本文从控制的角度研究了多智能体系统在DoS攻击下的一致性问题。所考虑的阻断代理组内信息交换的DoS攻击限制了攻击的频率和持续时间。提出了一种基于分布式观测器的控制器来重构agent的状态。我们证明了在DoS攻击下，所提出的控制器仍然可以达成共识。研究了DoS攻击同时干扰控制器和观测器通信网络的情况，得到了保持MASs一致性性能的充分条件。最后通过数值模拟对理论结果进行了验证。
This article studies the consensus problem of multiagent systems (MASs) subject to Denial-of-Service (DoS) attacks from the perspective of control. The considered DoS attacks blocking the information exchange in the group of agents pose limitations on the frequency and the duration of them. A distributed observer-based controller is proposed to reconstruct the states of the agents. We prove that MASs under DoS attacks can still achieve consensus by the proposed controller. The scenario where DoS attacks simultaneously jam both the communication networks associated with the controller and the observer is also addressed, and a sufficient condition is obtained to maintain the consensus performance of MASs. Finally, numerical simulations are provided to illustrate the theoretical results.
