Abstract

In this paper, the distributed event-triggered (ET) cooperative control problem is concerned for the nonlinear multi-agent systems (MASs) subject to time-delay and output constraint. Different from the traditional static constraint, the output constraint imposed in this paper is dynamic and asymmetric which is more challenging to handle with. A barrier function is employed to deal with the output constraint so that the systems can be converted to the unconstrained form. In order to overcome the time-delay, the Lyapunov-Krasovskii function is considered and a distributed ET consensus controller is designed via backstepping theory. The control signal will be released only if the triggered threshold is violated. Thus, all signals of closed-loop systems are cruelly proved to be bounded. Finally, the proposed control strategy is verified to be effective through a numerical experiment, which ensures the consensus of MASs and reduces communication burden.

具有时间延迟和输出约束的非线性多代理系统的分布式事件触发合作饱和控制

本文关注的是非线性多代理系统（MAS）的分布式事件触发（ET）协同控制问题，该问题受到时间延迟和输出约束的影响。与传统的静态约束不同，本文中的输出约束是动态和非对称的，处理起来更具挑战性。本文采用障碍函数来处理输出约束，从而将系统转换为无约束形式。为了克服时间延迟，考虑了 Lyapunov-Krasovskii 函数，并通过反步态理论设计了分布式 ET 共识控制器。只有在违反触发阈值时，控制信号才会被释放。因此，闭环系统的所有信号都被证明是有界的。最后，通过数值实验验证了所提出的控制策略是有效的，既保证了 MAS 的共识，又减轻了通信负担。

期刊介绍： Systems and control studies provide a unifying framework for a wide range of engineering disciplines and industrial applications. The Journal of Systems and Control Engineering refleSystems and control studies provide a unifying framework for a wide range of engineering disciplines and industrial applications. The Journal of Systems and Control Engineering reflects this diversity by giving prominence to experimental application and industrial studies. "It is clear from the feedback we receive that the Journal is now recognised as one of the leaders in its field. We are particularly interested in highlighting experimental applications and industrial studies, but also new theoretical developments which are likely to provide the foundation for future applications. In 2009, we launched a new Series of "Forward Look" papers written by leading researchers and practitioners. These short articles are intended to be provocative and help to set the agenda for future developments. We continue to strive for fast decision times and minimum delays in the production processes."
