Abstract

This paper proposes a distributed gain-scheduled observer-based technique for the practical state consensus of linear parameter-varying (LPV) multi-agent systems (MAS). In the proposed approach, the effects of considering different scheduling parameters for each agent are modeled as an internal disturbance. By applying the concepts of the Lyapunov theory, sufficient conditions are obtained for the design of a gain-scheduled observer-based consensus protocol ensuring that the trajectories of the consensus error converge exponentially to a bounded region, achieving a practical consensus. Numerical experiments illustrate the advantages of the proposed practical consensus over the non-synchronization-based scenario usually obtained when the LPV MAS is subjected to different scheduling parameters.

基于分布式增益调度观测器的LPV多智能体系统实际一致性方法

针对线性变参多智能体系统（MAS）的实际状态一致性问题，提出了一种基于分布式增益调度观测器的方法。在该方法中，考虑不同调度参数对每个智能体的影响被建模为内部扰动。应用Lyapunov理论的概念，得到了设计基于增益调度观测器的共识协议的充分条件，保证共识误差的轨迹指数收敛于有界区域，从而实现了实际的共识。数值实验表明，在LPV MAS受不同调度参数约束时，所提出的实际共识优于通常的非基于同步的场景。

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.
