摘　　要：本文研究了具有时间延迟的异结构不确定网络之间的外同步问题.基于Lyapunov稳定性理论,采用双向耦合自适应方法实现了两个结构互异的复杂网络之间的外同步.并且,网络的拓扑结构以及耦合强度也被同时确定.在数值模拟中,选取Van der Pol系统和Duffing系统作为网络节点进行仿真模拟,验证其理论结果的有效性.Outer synchronization between two uncertain time-varying delayed networks with diverse structures is investigated in this paper. Based on Lyapunov stability theory, we achieve synchronization between two time-varying delayed networks with diverse structures by using bidirectional coupling adaptive method. The network topology and coupling strength are indentified simultaneously in the synchronization process. Finally, Van der Pol system and Duffing system are taken as nodes to constitute networks, and simulation is performed to verify the effectiveness of the method.
