拉伸式3-D多涡卷混沌系统的设计及其在保密通信中的应用
资料介绍
基于典型的Chua式电路,提出了一种拉伸式多涡卷混沌系统。首先,通过系统的对称性、不变性、耗散性、系统平衡点和稳定性,分析了混沌的分维特性、时域波形、Lyapunov指数谱等基本的混沌动力学特性。其次,利用PSPICE实现了该系统的混沌电路。最后,结合Lyapunov稳定性原理,运用单向耦合法,探究了该混沌系统的同步性问题,并采用该方法有效地实现了特定信号的加密、解密。数值仿真与实验结果保持一致,进一步证实了该方法的可行性。
A kind of tensile-type 3-D multi-scroll chaotic attractor based on Chua＇s circuit was successfully designed. The chaos generation mechanism was studied by analyzing the symmetry and invariance, the existence of the dissipation, as well as the system equilibrium and stability. Then, some basic dynamical properties, such as Lyapunov exponents, fractal dimension, chaotic dynamical behaviors of the new chaotic system were introduced, either numerically or analytically. At the same time, the chaotic circuit of this system was realized by PSPICE. Finally, based on Lyapunov theorem and unidirectionally coupled method, the synchronization of the chaotic system has also been investigated. With this approach, the novel system can be ap...
