This article is concerned with the problem of finite-time mixed outer synchronization (FMOS) of complex networks with coupling time-varying delay. FMOS is a recently developed generalized synchronization concept, i.e., in which different state variables of the corresponding nodes can evolve into finite-time complete synchronization, finite-time anti-synchronization, and even amplitude finite-time death simultaneously for an appropriate choice of the controller gain matrix. Some novel stability criteria for the synchronization between drive and response complex networks with coupling time-varying delay are derived using the Lyapunov stability theory and linear matrix inequalities. And a simple linear state feedback synchronization controller is designed as a result. Numerical simulations for two coupled networks of modified Chua's circuits are then provided to demonstrate the effectiveness and feasibility of the proposed complex networks control and synchronization schemes and then compared with the proposed results and the previous schemes for accuracy.
本文研究了具有时变耦合延迟的复杂网络的有限时间混合外同步(FMOS)问题。FMOS 是一种最近发展起来的广义同步概念,即通过适当选择控制器增益矩阵,可以使相应节点的不同状态变量同时演化为有限时间完全同步、有限时间反同步,甚至是幅度有限时间死亡。利用 Lyapunov 稳定性理论和线性矩阵不等式,得到了具有时变耦合延迟的驱动和响应复杂网络同步的一些新的稳定性准则。结果设计了一个简单的线性状态反馈同步控制器。然后,通过两个改进的蔡氏电路耦合网络的数值仿真,验证了所提出的复杂网络控制和同步方案的有效性和可行性,并与所提出的结果和以前的方案进行了精度比较。
