摘要
计算机技术、网络技术和通信技术的飞速发展,推动着无人驾驶飞行器的编队控制、传感器网络的分布控制、卫星的姿态控制等多智能体系统的建模与应用的逐步深入,也吸引了越来越多的研究者致力于多智能体系统的动态编队控制的研究.研究了具有不同的通信时延和不同的输入时延的移动多智能体算法的群集运动.假设多智能体系统由n个智能体和1个Leader组成,网络连接拓扑是静态有向连通图,智能体Leader为拓扑图的全局可达节点.应用频率域的广义Nyquist判据分析了具有不同的通信时延和不同的输入时延的移动多智能体算法,应用Greshgorin圆盘定理和曲线的曲率理论研究了具有领航者的多智能体算法的群集运动,得到保证系统一致性的收敛条件.该一致性条件是一个应用节点局部信息的分散式条件,只与输入时延有关,而与通信时延无关.最后,通过计算机仿真验证了本文结论的有效性.
With the development of computer technology,network technology and communication technology,it is deeply promoted for the modeling and application of the multi-agent systems including the alignment control of unmanned air vehicles(UAVs),the distribution control of the sensor network,and the pose control of the satellite.Recently,there are more and more researchers to bend their minds to study the dynamical alignment control of the multi-agent systems.In this paper,flocking movement of mobile multi-agents system with heterogeneous communication delays and heterogeneous input delays is studied.Suppose the multi-agent systems consist of n agents and a leader,there is a static directed interconnected graph with leader as a globally reachable node.By applying the generalized Nyquist criterion of the frequency domain,the consensus algorithm with heterogeneous communication delays and heterogeneous input delays is analyzed.By utilizing the Greshgorin's disc theorem and curvature theory,the flocking motion of delayed multiple-agent algorithm with leader-following is studied,and a decentralized consensus convergence condition is obtained to ensure the flocking movement of the multi-agent systems.This consensus condition applies the local information of every agent,which is dependent on input delays but independent of communication delays.Finally,computer simulation is used to show the validity of the results.
