Abstract

This paper is concerned with the leaderless output consensus control problem for uncertain nonlinear multi-agent systems with mismatched unknown parameters. Different from currently available results, the considered agents are allowed to have heterogenous and arbitrary system orders. To solve such consensus problem, a novel distributed reference system, whose output serves as a local reference signal, is first designed for each agent. Then, under directed interaction topology condition, a fully distributed leaderless output consensus control scheme is proposed based on adaptive backstepping technique, by using only relative outputs of neighboring agents. It is shown that with the proposed control scheme, all the closed-loop signals are globally uniformly bounded and all the agents’ outputs can reach consensus. Finally, an application example is utilized to verify the effectiveness of the proposed control scheme.

具有异源系统阶次的不确定非线性多代理系统的分布式自适应无领导输出共识

本文关注的是具有不匹配未知参数的不确定非线性多代理系统的无领导输出共识控制问题。与现有成果不同的是，所考虑的代理允许具有异质和任意的系统阶数。为了解决这种共识问题，首先为每个代理设计了一个新颖的分布式参考系统，其输出可作为局部参考信号。然后，在有向交互拓扑条件下，基于自适应反步进技术，仅使用相邻代理的相对输出，提出了一种全分布式无领导输出共识控制方案。结果表明，在所提出的控制方案下，所有闭环信号都是全局均匀有界的，所有代理的输出都能达成共识。最后，通过一个应用实例验证了所提控制方案的有效性。

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.
