Generalized Synchronization of Chaotic System with Constant Lyapunov Exponent Spectrum

摘要/Abstract

摘要:

文献[11]提出了一种恒Lyapunov指数谱混沌系统,该系统存在一个局部变幅参数,能够线性调整输出混沌信号中的两维信号的幅值,而不改变其混沌动力学特性。利用广义同步的方法,研究了该恒Lyapunov指数谱混沌系统的同步控制,使用混沌遮掩的方法进行了数值仿真实验。结果证明了广义同步方案的有效性,并指出了应用前景。

Abstract:

A constant-Lyapunov-exponent-spectrum chaotic system was proposed by Li et al where exists a special local amplitude modulation parameter changing the amplitudesof certain two signals generated by the system in linearity while the dynamical behavior keeps on invariable at the same time. By means of generalized synchronization, synchronized control of chaotic system with constant Lyapunov exponent spectrum is studied.Meanwhile the method of chaotic hiding is used to do experimentsof numerical simulation . The result proves the effectiveness of generized synchronization of this spectial chaotic system , and its application prospect is pointed out.
