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.

执行器故障下线性多智能体系统的分布式二分自适应事件触发容错共识跟踪


本文考虑基于输出反馈控制协议的执行器故障存在情况下线性多智能体系统的分布式二分自适应事件触发容错一致性跟踪问题。同时考虑时变加法和乘法执行器故障。并且不需要知道执行器故障的上/下限。首先，状态观测器旨在解决不可测量的系统状态的发生。然后开发了两种事件触发机制来调度代理间通信和控制器更新。接下来，利用开发的事件触发机制，提出了一种新颖的基于观测器的双向自适应控制策略，可以解决容错控制问题。与该主题的一些相关工作相比，我们的控制方案可以实现间歇性通信和间歇性控制器更新，并且考虑了更一般的执行器故障和网络拓扑。证明了Zeno行为的排除是可以实现的。最后，给出了三个说明性例子来证明主要理论结果的可行性。
