基于Lyapunov指数Duffing混沌检测系统状态的判定

The Judgment of the States of the Duffing Chaotic Detection System based on the Lyapunov Exponent

  • 摘要: 为解决Duffing混沌检测系统状态判定的准确性,克服直观相图判定法存在的不足,提出了采用Lyapunov指数定量地判定Duffing混沌检测系统状态的方法.在分析判定方法及Duffing系统中Lyapunov指数算法的基础上,进行了系统仿真和数据分析,结果验证了利用Lyapunov指数判定Duffing系统状态的可行性,从而能有效地应用于微弱信号检测,保证信号检测的可靠性

     

    Abstract: In order to solve the accuracy of the judgment of chaos detection system’s states and to cast off defaults of the intuitive phase judgment method,this paper adopts the Lyapunov exponent to quantitatively judge states of the Duffing chaos detection system.Based on the analysis method and the algorithm of the Lyapunov exponent,we carried out the system simulation and data analysis.The result certifies the feasibility of using Lyapunov exponent to judge the states of the Duffing chaotic detection s...
