中文摘要：

在这份报纸，一个组一致问题与所有代理人被 Euler-Lagrange 系统与不明确的参数管理的参量的无常为多重联网的代理人被调查。处于组一致问题，代理人 asymptotically 到达几个不同状态而非一个一致状态。一个新奇的组一致协议和不明确的参数的一个变化时间的评估者被建议让每个代理人以便解决夫妇组一致问题。甚至当系统包含不明确的参数时，组一致是可达到的，这被显示出甚至当系统包含不明确的参数时。而且，多组一致作为夫妇组一致的延期被讨论，然后有交换拓扑学的组一致被考虑。模拟结果最后被提供验证理论分析的有效性。

英文摘要：

In this paper,a group consensus problem is investigated for multiple networked agents with parametric uncertainties where all the agents are governed by the Euler-Lagrange system with uncertain parameters.In the group consensus problem,the agents asymptotically reach several different states rather than one consistent state.A novel group consensus protocol and a time-varying estimator of the uncertain parameters are proposed for each agent in order to solve the couple-group consensus problem.It is shown that the group consensus is reachable even when the system contains the uncertain parameters.Furthermore,the multi-group consensus is discussed as an extension of the couple-group consensus,and then the group consensus with switching topology is considered.Simulation results are finally provided to validate the effectiveness of the theoretical analysis.
