摘要
从动力学与控制的角度考虑具有固定与切换拓扑多个体时滞有向网络系统的平均一致性问题.基于时滞动力系统的脉冲控制理论,提出了在通讯时滞环境中两个网络的脉冲一致性协议,并给出了寻求相应平均一致性问题简单而又一般的判据.最显著的特征是提出的第一个一致性协议对于任意的通讯时滞都是有效的,第二个一致性协议能够使得整个网络指数地达到平均一致.所获得结果表明,一致性协议中的脉冲增益在寻求平均一致性问题中具有相当重要的作用.数值模拟进一步验证了理论结果的正确性.
This paper considers average consensus problems in directed delayed networked multi-agent systems having fixed topology as well as switching topology from the view of dynamics and control.Based on the impulsive control theory of delayed dynamical systems,two consensus protocols of the networks with communication delays are proposed.Some simple yet generic criteria for solving the average consensus problem are analytically derived.The distinctive features of this work indicate that the first consensus protocol is valid for any communication delays,and the second one is effective for all the nodes of the network achieving average global consensus exponentially.It is shown that the impulsive gain in the protocols plays a key role in seeking average consensus.Moreover,numerical simulations illustrate correctness of our theoretical results.
