In this paper, the distributed adaptive event-triggered fault-tolerant consensus of general linear multiagent systems (MASs) is considered. First, in order to deal with multiplicative fault, a distributed event-triggered consensus protocol is designed. Using distributed adaptive online updating strategies, the computation of the minimum eigenvalue of Laplacian matrix is avoided. Second, some adaptive parameters are introduced in trigger function to improve the self-regulation ability of event-triggered mechanism. The new trigger threshold is both state-dependent and time-dependent, which is independent of the number of agents. Then sufficient conditions are derived to guarantee the leaderless and leader-following consensus. On the basis of this, the results are extended to the case of actuator saturation. It is proved the Zeno-behavior of considered event-triggered mechanism is avoided. At last, the effectiveness of the proposed methods are demonstrated by three simulation examples.

具有通用线性动力学的多智能体系统的分布式自适应事件触发容错共识

本文考虑了通用线性多主体系统（MAS）的分布式自适应事件触发容错共识。首先，为了处理乘法故障，设计了一种分布式事件触发共识协议。使用分布式自适应在线更新策略，避免了拉普拉斯矩阵的最小特征值的计算。其次，在触发函数中引入了一些自适应参数，以提高事件触发机制的自调节能力。新的触发阈值既取决于状态又取决于时间，这与代理的数量无关。然后得出足够的条件来确保无领导者和领导者遵循共识。在此基础上，将结果扩展到执行器饱和的情况。事实证明，可以避免考虑事件触发机制的Zeno行为。最后，通过三个仿真实例证明了所提方法的有效性。
