Abstract

Distributed event-triggered control improves resource efficiency by updating control inputs only when necessary. Most existing related studies focus primarily on steady-state performance, often overlooking transient behavior. This paper proposes novel prescribed performance adaptive distributed event-triggered control schemes for networked second-order integrator multi-agent systems, ensuring time-varying consensus even in the presence of disturbances. Specifically, intermittently updated edge-based measurement information is employed for event-triggered feedback control to conserve limited resources. Adaptive gains are designed to eliminate the requirement for global network information during implementation. By incorporating appropriate performance functions, the proposed control schemes guarantee that the relative position and velocity errors satisfy the prescribed transient and steady-state performance bounds. An explicit lower bound on the inter-event intervals within any finite time horizon is derived, revealing the relationship between control performance and triggering frequency. Numerical simulations are provided to demonstrate the effectiveness, superiority, and applicability of the developed control schemes.

规定的性能分布式事件触发控制

分布式事件触发控制仅在必要时更新控制输入，从而提高了资源效率。现有的大多数相关研究主要集中在稳态性能上，往往忽略了瞬态行为。针对网络二阶积分器多智能体系统，提出了一种新的规定性能的自适应分布式事件触发控制方案，即使在存在干扰的情况下也能保证时变一致性。具体来说，基于边缘的测量信息的间歇更新被用于事件触发的反馈控制，以节省有限的资源。自适应增益的设计是为了消除在实现过程中对全局网络信息的需求。通过引入适当的性能函数，所提出的控制方案保证了相对位置和速度误差满足规定的瞬态和稳态性能界限。导出了任意有限时间范围内事件间间隔的显式下界，揭示了控制性能与触发频率之间的关系。数值仿真验证了所提出的控制方案的有效性、优越性和适用性。

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.
