Abstract

This paper studies the distributed consensus control for linear multi-agent systems under discontinuous communication and control updating. A fully distributed event-triggered adaptive control protocol with strictly positive minimum interevent time (MIET) guarantees is proposed. First, an event-triggered distributed adaptive control law without using prior global information of network topologies is presented, which achieves asymptotic consensus via discrete control updating and intermittent communication. Then, a hybrid adaptive event-triggering scheme with an internal timer is designed that is activated only when the timer decreases to zero from a specified positive value. Under the proposed triggering scheme, not only Zeno behavior is excluded but also a strictly positive MIET between any two consecutive events is guaranteed, which facilitates the physical implementation. In contrast to the existing related results, the proposed fully distributed protocol only needs low-frequency communication and control updating, while ensuring the strictly positive MIET property. Finally, a simulation example is given to illustrate the effectiveness of the theoretical results.

具有间歇通信和控制更新功能的混合自适应事件触发共识控制
本文研究了线性多代理系统在不连续通信和控制更新条件下的分布式共识控制。本文提出了一种严格保证最小事件发生时间(MIET)的全分布式事件触发自适应控制协议。首先,提出了一种不使用网络拓扑的先验全局信息的事件触发分布式自适应控制法则,通过离散控制更新和间歇通信实现渐近共识。然后,设计了一种带有内部定时器的混合自适应事件触发方案,只有当定时器从指定的正值下降到零时才会被激活。在所提出的触发方案下,不仅排除了芝诺行为,而且还保证了任意两个连续事件之间严格的正 MIET,这为物理实现提供了便利。与现有的相关成果相比,所提出的全分布式协议只需要低频率的通信和控制更新,同时还能确保严格的正 MIET 特性。最后,给出了一个仿真实例来说明理论结果的有效性。
