Abstract

This paper addresses the leader-following consensus problem for general linear multiagent systems under general directed topology, with a focus on the scenarios where only relative output information is available. To solve such problem, most existing observer-based protocols rely on relative observer information among neighboring agents, which is obtained through the communication network and can be susceptible to network attacks. To overcome this limitation, this paper proposes a novel class of distributed observer-based linear time-varying protocols, in which the feedback gain is designed with two time-varying terms, one of which tends towards infinity as time increases, while the other tends towards zero. Compared to existing protocols, the proposed protocols offer significant advantages. Notably, they do not require information exchange through the communication network, making them immune to network attacks. Furthermore, the protocols operate in a fully distributed manner, which makes them resilient to changes in the topology graph. Simulation results demonstrate the effectiveness of the proposed approach.

基于线性时变反馈的线性多智能体系统的完全分布式和攻击免疫协议

本文研究了一般有向拓扑下的一般线性多智能体系统的领导-跟随一致性问题，重点研究了只有相对输出信息可用的情况。为了解决这一问题，现有的大多数基于观测器的协议依赖于相邻代理之间的相对观测器信息，这些信息是通过通信网络获得的，容易受到网络攻击。为了克服这一限制，本文提出了一类新的基于分布式观测器的线性时变协议，该协议将反馈增益设计为两个时变项，其中一个时变项随着时间的增加趋于无穷大，而另一个时变项趋于零。与现有协议相比，所提出的协议具有显著的优势。值得注意的是，它们不需要通过通信网络交换信息，因此不受网络攻击的影响。此外，这些协议以完全分布式的方式运行，这使它们能够适应拓扑图的变化。仿真结果验证了该方法的有效性。

期刊介绍： Automatica is a leading archival publication in the field of systems and control. The field encompasses today a broad set of areas and topics, and is thriving not only within itself but also in terms of its impact on other fields, such as communications, computers, biology, energy and economics. Since its inception in 1963, Automatica has kept abreast with the evolution of the field over the years, and has emerged as a leading publication driving the trends in the field. After being founded in 1963, Automatica became a journal of the International Federation of Automatic Control (IFAC) in 1969. It features a characteristic blend of theoretical and applied papers of archival, lasting value, reporting cutting edge research results by authors across the globe. It features articles in distinct categories, including regular, brief and survey papers, technical communiqués, correspondence items, as well as reviews on published books of interest to the readership. It occasionally publishes special issues on emerging new topics or established mature topics of interest to a broad audience. Automatica solicits original high-quality contributions in all the categories listed above, and in all areas of systems and control interpreted in a broad sense and evolving constantly. They may be submitted directly to a subject editor or to the Editor-in-Chief if not sure about the subject area. Editorial procedures in place assure careful, fair, and prompt handling of all submitted articles. Accepted papers appear in the journal in the shortest time feasible given production time constraints.
