| 摘 要： | 利用非线性函数耦合混沌同步方法，研究蔡氏混沌系统的同步问题．依据线性系统的稳定性分析准则，证明耦合系数k = 0:5 时非线性函数耦合混沌系统的同步稳定性，并数值模拟检验其有效性．基于Routh-Hurwitz 稳定性判据，推导出非线性耦合强度的下限，即k > 0:427．将非线性函数耦合同步方法推广到完全连接网络，证明了网络同步的稳定性．在此基础上，利用混沌掩盖构造完全连接网络的保密通信系统，并通过数值仿真证明其可行性．

| Abstract: | By the synchronization method of coupled chaotic systems based on nonlinear function,the synchronization of Chua's chaotic system is investigated.When the coupling factor k = 0.5,the stability of the synchronous state of coupled chaotic systems based on nonlinear function is proved by the stability criterion of linear systems,and its validity is examined by numerical simulation.Based on the Routh-Hurwitz's stability criterion,the lower limit of the nonlinear coupling strength ensuring the synchronization is... |
