摘要:

        在耦合矩阵不对称并且假设耦合指数已知的条件下,利用 LyapunovKrasovskii稳定理论设计了一个非线性反馈控制器,使得复杂网络达到全局指数同步。通过数值仿真,证明了该同步定理的可行性和有效性。

关键词: 指数同步, 复杂网络, 时滞节点, Lyapunov函数, 权值网络

Abstract:

        We design a nonlinear feedback controller with LyapunovKrasovskii stability theory based on unsymmetry coupled matrix and the assumption of known coupling coefficients. We further implement the global exponential synchronization of a complex network. Numerical simulations demonstrate its feasibility and effectiveness.

Key words: exponential synchronization, complex networks, delayed nodes, Lyapunov function, directed and weighted network
