摘要:
针对混沌遥测系统的参数估计问题,研究了基于混沌同步的不同混沌时延系统的 参数估计方法。构造了利用不同混沌系统进行参数估计的自适应方案,利用Krasovskii -Lyapunov理论推导出两个不同混沌时延系统同步和参数估计的充分条件。所提方案应用到 混沌遥测系统参数估计可以有效估计系统参数。非合作者可用所构造方法利用不同混沌 系统获取混沌遥测系统的有用信息。仿真分析验证了方案的有效性。

Parameters Estimation of Chaotic Telemetry System between Two Different Time-delayed Chaotic Systems

Abstract:
For parameter estimation of chaotic telemetry system, chaos synchroniz ation based parameter estimation between two different time-delayed chaotic syst ems is investigated. An adaptive scheme is proposed to estimate all the parameter s of the interested system using a different system. Sufficient conditions for s ynchronization and parameter estimation are shown analytically according to Kra sovskii-Lyapunov theory.By using the parameter estimation scheme in chaotic telemetry signal reconnaissance,the message transmitted can be recovered effect ively. The proposed scheme can be used to obtain useful information of chaotic telemetry system between two different chaotic systems by non-cooperator. Numerical simulations illustrate the validit y of the scheme.
