摘要

本文研究了具有乘性噪声和有向拓扑的线性多智能体系统的事件触发全局和群体一致问题。首先，对于平衡有向图下质量的全局一致性，证明了输入到状态的随机稳定性，证明了分段常数控制输入具有足够的反馈能力；基于相对状态测量，建立了两种新的静态和动态事件触发机制（etm）来减少控制器更新次数，其中通过对所有事件间时间施加统一严格固定的正时间，有效消除了芝诺现象。特别是发展了新的随机稳定性分析技术，给出了静态和动态etm均方的充分条件和几乎确定的一致性。此外，为了解决实际应用中的一些分组任务，将关于全局共识的研究结果推广到群体共识的设置上。最后，通过算例验证了理论结果的有效性。

Event-triggered global and group consensus for linear multiagent systems with multiplicative noises

This article is concerned with the event-triggered global and group consensus problems for linear multiagent systems (MASs) with multiplicative noises and directed topology. First, for the global consensus of MASs under a balanced directed graph, a stochastic input-to-state stability property is proved to show that the piecewise constant control input has sufficient feedback capability; based on the relative state measurement, two novel static and dynamic event-triggered mechanisms (ETMs) are established to reduce the number of controller updates, where the Zeno phenomenon is effectively eliminated by imposing a uniformly strictly fixed positive time for all the inter-event times. Especially, new stochastic stability analysis techniques are developed to give sufficient conditions of mean square and almost sure consensus in both static and dynamic ETMs. Moreover, the obtained results on global consensus are extended to the setting of group consensus in order to cope with some grouping tasks in practical applications. Finally, some examples are presented to show the validity of theoretical results.

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.
