摘要

研究了具有不确定时变时滞的多智能体系统有向网络的平均一致性问题。首先分析了保持弱连接和弱平衡的固定拓扑和交换拓扑。然后将原始系统转换为降维模型。基于Jensen不等式和互凸方法，进一步给出了平均一致的充分条件。特别地，通过与已有结果的比较，导出了时变通信延迟的保守性较低的上界。数值算例验证了该方法的有效性。

Average Consensus in Directed Networks of Multi-agents with Uncertain Time-varying Delays

This paper investigates the average consensus problem in directed networks of multi-agent systems with uncertain time-varying delays. Fixed and switching topologies that are kept weakly connected and balanced are firstly analyzed. The original system is then transformed into a reduced dimension model. Based on Jensen's inequality and reciprocally convex approach, sufficient conditions for average consensus are further presented. Specially, a less conservative upper bound of time-varying communication delays is derived in comparison with the existing results. Numerical examples confirm the effectiveness of the proposed method.
