针对由多个子网络构成的双时变时滞复杂网络系统,首先给出子网间交叉同步定义,设计周期间歇控制器,讨论此类系统的同步稳定问题.利用李亚普诺夫稳定性理论并结合零点定理,得出了具有可变时滞特性复杂网络系统网络间同步指数稳定周期间歇控制器存在的充分条件.同时本文就复杂网络系统节点间关系进行了讨论,复杂网络系统中的两节点必须在满足连接且可相互影响的基础上才具有实际耦合强度.最后结合所给条件,给出一个数值仿真说明其有效性.
Aiming at the dual-time-varying and time-varying complex network system composed of multiple subnetworks, firstly, the definition of cross-subnet synchronization and the design cycle intermittent controller are discussed to discuss the synchronization and stability problems of such systems. By using Lyapunov stability theory and combining The sufficient conditions for the existence of the periodic exponential stable periodic intermittent controller for complex network systems with variable delay characteristics are obtained.The relationship between nodes in complex network systems is discussed in this paper.The two nodes in complex network system must And it has the strength of actual coupling on the basis of satisfying the connection and mutual influence.Finally, according to the given conditions, a numerical simulation is given to show its effectiveness.
