在本研究中，提出了一种仅使用触发信息的分布式事件触发方案（ETS）来解决一类具有一般线性动力学的多智能体系统在固定拓扑和切换拓扑下的领导者跟随共识问题。首先，利用相邻智能体在触发时间的离散通信，提出了一种新的固定拓扑触发条件，消除了智能体间的连续通信，同时降低了控制器更新的频率。其次，对于交换拓扑，包括有向生成树的图和没有有向生成树的图，作者提出了拓扑相关的分布式ETS，通过平均停留时间方法保证一致性。值得注意的是，在固定拓扑和切换拓扑下，触发时间序列的芝诺行为被排除在外。实例验证了该方法的有效性，并通过比较显示了该方法的优越性。
In this study, a novel distributed event‐triggered scheme (ETS) using only triggered information is presented to solve the problem of the leader‐following consensus for a class of multi‐agent systems with general linear dynamics under fixed and switching topologies. First, the novel triggering conditions are proposed for fixed topology by virtue of discrete communications between neighbouring agents at the triggering times, which eliminates continuous inter‐agent communication and reduces the frequency of controller update simultaneously. Second, for switching topology including both graphs that have directed spanning tree and graphs that do not, the authors propose the topology‐dependent distributed ETS to guarantee consensus by an average dwell time approach. Noteworthily, Zeno behaviour of triggering time sequences is excluded under fixed and switching topologies. Examples validate the effectiveness and show the advantage of the proposed ETS by comparison.
