Abstract

This article considers the leader-following consensus problem of multiagent systems subject to unbounded distributed communication delays under the condition that only the neighboring agents of the leader have access to the information on both the system matrix and the state of the leader. A novel adaptive distributed observer is proposed to estimate both the system matrix and the state of the leader under unbounded distributed communication delays, without requiring that the information of the unbounded delays is known a priori. A key technical result is first established, and a novel distributed controller is then developed based on the proposed distributed observer. It is shown that the resulting closed-loop system achieves the desired consensus. Finally, the effectiveness of the theoretical results is validated by two simulation examples.

基于自适应分布式观测器的无界通信延迟下多智能体系统的一致性

考虑了具有无界分布式通信延迟的多智能体系统中，只有领导者的相邻智能体可以同时访问系统矩阵和领导者状态信息的情况下，领导者-跟随一致性问题。提出了一种新的自适应分布式观测器，在不需要先验地知道无界延迟信息的情况下，对无界延迟下的系统矩阵和leader状态进行估计。首先确定了关键技术成果，然后基于所提出的分布式观测器开发了一种新的分布式控制器。结果表明，所得到的闭环系统达到了期望的一致性。最后，通过两个仿真算例验证了理论结果的有效性。
