摘要

本文通过事件触发间歇通信和采样数据控制两种方法，研究了非线性多代理系统（MAS）的固定时间（FXT）共识问题。首先，结合事件触发机制和集中采样数据控制方法，设计了一种新型的事件触发间歇控制协议，其中引入了辅助函数来确定协议的控制间隔。其次，集中式策略需要获取全局信息，在大规模网络中可能难以应用。因此，我们设计了一种采用分布式采样数据控制策略的间歇通信协议，其中事件触发条件仅通过本地邻居的状态给出。此外，基于李亚普诺夫稳定性理论，我们得到了一些充分条件，以实现采用集中式和分布式采样数据控制策略的 MAS 的 FXT 共识，并避免了 Zeno 现象。最后，通过两个实例验证了理论结果的正确性。

Fixed-time consensus of nonlinear multi-agent systems via both event-triggered intermittent communication and sampled-data control

This paper investigates the fixed-time (FXT) consensus issue for nonlinear multi-agent systems (MASs) via both event-triggered intermittent communication and sampled-data control. Firstly, combining the event-triggered mechanism and the centralized sampled-data control method, a new type of the event-triggered intermittent control protocol is devised, in which the auxiliary function is introduced to determine the control intervals of the protocol. Secondly, the centralized strategy, which requires obtaining the global information, may be difficult to apply in large-scale networks. Therefore, we design an intermittent communication protocol with the distributed sampled-data control strategy, in which the event-triggering condition is given only by using local neighbors’ states. Furthermore, based on the Lyapunov stability theory, some sufficient conditions are obtained for achieving FXT consensus of MASs with the centralized and distributed sampled-data control strategies, and the Zeno phenomena are avoided. Finally, two examples are provided to verify the validity of the theoretical results.
