This article considers the distributed bipartite adaptive event-triggered fault-tolerant consensus tracking issue for linear multiagent systems in the presence of actuator faults based on the output feedback control protocol. Both time-varying additive and multiplicative actuator faults are taken into account in the meantime. And the upper/lower bounds of actuator faults are not required to be known. First, the state observer is designed to settle the occurrence of unmeasurable system states. Two kinds of event-triggered mechanisms are then developed to schedule the interagent communication and controller updates. Next, with the developed event-triggered mechanisms, a novel observer-based bipartite adaptive control strategy is proposed such that the fault-tolerant control problem can be addressed. Compared with some related works on this topic, our control scheme can achieve the intermittent communication and intermittent controller updates, and the more general actuator faults and network topology are considered. It is proved that the exclusion of Zeno behavior can be realized. Finally, three illustrative examples are given to demonstrate the feasibility of the main theoretical findings.

线性多主体系统在执行器故障下的分布式两方自适应事件触发的容错共识跟踪。

本文考虑了基于输出反馈控制协议的执行器故障情况下线性多主体系统的分布式双方自适应事件触发的容错共识跟踪问题。同时考虑了时变的加性和乘性执行器故障。并且不需要知道致动器故障的上限/下限。首先，状态观察器旨在解决无法测量的系统状态的发生。然后，开发了两种事件触发机制来安排代理之间的通信和控制器更新。接下来，利用已开发的事件触发机制，提出了一种新颖的基于观察者的双向自适应控制策略，从而可以解决容错控制问题。与与此主题相关的一些作品相比，我们的控制方案可以实现间歇性的通讯和间歇性的控制器更新，并考虑了更一般的执行器故障和网络拓扑。事实证明，可以实现对芝诺行为的排斥。最后，给出了三个说明性的例子来说明主要理论发现的可行性。
