摘要:

讨论了一类变时滞的不同复杂网络间的线性广义同步问题。基于Lyapunov 稳定性理论和自适应控制方法,得到了网络线性广义同步的充分条件。此外,每个网络中的节点和耦合项均含有时滞函数,且网络的维数不同、拓扑结构不恒等,每个网络节点的动力学也可以不同。最后数值模拟结果证实了该方法的合理性,并验证了同步速度受自适应律强度的影响。

Abstract:

Generalized linear synchronization of different complex networks with time-varying delays is introduced. Based on Lyapunov stability theory,some generalized linear synchronization sufficient conditions are derived by adaptive control method. Furthermore,each network with time -varying coupling delays and time -varying delays in dynamical nodes may have different dimensions and its topological structure is also nonidentical. Nodes in either network may have identical or different dynamics. A numerical simulation example is also provided to testify the rationality of the current method,demonstrating that the synchronization rate is affected by adaptive law strengt

Key words: different complex networks, generalized linear synchronization, time-varying delays, adaptive controller
