摘要: 针对具有不同拓扑结构的一阶、二阶多智能体网络,基于频域控制理论,分别研究了其在多时滞影响下的分组一致性问题,分析并给出系统渐近实现分组一致的代数条件判据。研究发现多智能体网络分组一致的实现要同时受到节点自身输入时滞以及节点间耦合权重的影响,与节点间的通信时滞无关,但会影响系统的收敛速度。仿真实验的结果进一步验证了理论分析所得结论的正确性与有效性。

Abstract: The group consensus problems for first-order and second-order multi-agent networks with multiple time delays are investigated respectively. Based on the theory of frequency-domain, some algebraic criteria are analytically proposed, which can guarantee the achievement of group consensus. The results show that the input time delays, the coupling weights and the coupling strengths between the agents play key roles in reaching group consensus, whereas communication time delays can only affect the convergence rate of the systems. The validity of the results is verified by several simulated examples.

Key words: time delays, group consensus, multi-agent networks, complex networks
