This paper concentrates on the design of an event-triggered communication strategy for secondary multi-agent systems. Many existing results in this field usually require centralized information depending on the Laplacian matrices. In a real application, however, such the constraint is conservative. To address it, this paper proposes an event-triggered sampling mechanism for interagent communication with updated thresholds. Accordingly, consensus protocols with adaptive coupling control gains are proposed for both a fixed topology and switching topologies. It is proven that the proposed method guarantees the leader-following consensus for second-order multiagent systems with an arbitrarily connected topology and even with jointly connected switching topologies. The effectiveness of the proposed scheme is verified by simulation examples.
本文主要研究二级多智能体系统的事件触发通信策略设计。该领域许多现有成果通常需要依赖拉普拉斯矩阵的集中式信息。然而，在实际应用中，这种约束过于保守。为解决这一问题，本文提出一种具有更新阈值的智能体间通信事件触发采样机制。相应地，针对固定拓扑和切换拓扑，提出了具有自适应耦合控制增益的一致性协议。结果表明，该方法能保证任意连通拓扑甚至联合连通切换拓扑的二阶多智能体系统实现领导者跟随一致性。仿真示例验证了所提方案的有效性。
