摘要

给出了一类基于线性状态观测器混沌或超混沌同步的方案

并将其应用到混沌保密通信中。对观测器的理论分析表明

该方案的同步误差收敛速率是由观测器的增益参数θ来决定的;θ越大

同步误差的收敛速率越快。最后通过对R?ssler系统的仿真研究

验证了该方案的有效性。

Abstract

A linear state observer based synchronization scheme for a class of chaotic systems was presented

and this scheme was applied to secure communication. The analysis result to the observer showed that the system’s convergence rate of the synchronization error depends on the parameter θ of observer gain

in the sense that the larger the value of θ

the faster the convergence. Finally

a simulation of R?ssler system effectively exploits the proposed scheme’s effectiveness.
