摘要: 针对一类具有变时滞非线性耦合的不确定复杂动态网络,研究其指数同步问题.同时考虑复杂网络模型中变时滞和网络的不确定性,在节点的动态变化及节点间的耦合均为非线性条件下,假设不确定项满足匹配条件,变时滞未知但有界,通过构造合适的Lyapunov-Krasovskii泛函,利用线性矩阵不等式等分析方法设计了合适的反馈控制器,得到一类具有变时滞的不确定复杂动态网络指数同步的新判据.最后,通过仿真验证了所提出控制设计的有效性.

Abstract: This paper focuses on the exponential synchronization problems of uncertain complex dynamic networks with time-varying delay. Both time-varying delays and network uncertainties of the complex dynamic network model are considered. As the dynamic changes of nodes and the coupling between nodes are nonlinear, under the condition that the uncertainty satisfies the matching condition and that the delay is unknown but bounded, a new criterion of the exponential synchronization is derived by constructing a suitable Lyapunov-Krasovskii function with the linear matrix inequality (LMI) approach. And the appropriate feedback controllers are designed. Finally, numerical simulation validates the effectiveness of the proposed method.

Key words: uncertain, linear matrix inequality (LMI), exponential synchronization, time-varying delay, complex network
