研究了基于自适应非周期间歇控制的有色社区网络钉扎簇同步问题。首先,提出了一个通用的有色社区网络模型,其中孤立的节点可以通过不同社区中的不同连接进行交互,不同对社区之间的交互也可以是不同的,并且不同社区中的节点可以具有不同的状态维度。在此基础上,提出了一种自适应非周期性间歇控制策略,并结合钉扎机制实现了该有色社区网络的簇同步。通过引入一种新的分段连续辅助函数,根据Lyapunov稳定性理论和分段分析方法,严格推导了全局指数簇同步准则。基于所导出的准则,给出了说明每个社区中的哪些节点应该被优先钉住的准则。需要注意的是,自适应间歇钉扎控制是非周期的,其中允许控制宽度和控制周期两者可变。最后,给出了一个数值算例,验证了理论结果的有效性。
This paper investigates the problem of pinning cluster synchronization for colored community networks via adaptive aperiodically intermittent control. Firstly, a general colored community network model is proposed, where the isolated nodes can interact through different kinds of connections in different communities and the interactions between different pair of communities can also be different, and moreover, the nodes in different communities can have different state dimensions. Then, an adaptive aperiodically intermittent control strategy combined with pinning scheme is developed to realize cluster synchronization of such colored community network. By introducing a novel piecewise continuous auxiliary function, some globally exponential cluster synchronization criteria are rigorously derived according to Lyapunov stability theory and piecewise analysis approach. Based on the derived criteria, a guideline to illustrate which nodes in each community should be preferentially pinned is given. It is noted that the adaptive intermittent pinning control is aperiodic, in which both control width and control period are allowed to be variable. Finally, a numerical example is provided to show the effectiveness of the theoretical results obtained.
