摘要:

为产生复杂的混沌吸引子,构造了一个由三个子系统组成的自动切换混沌系统。该系统通过模拟开关,能够在3个子系统之间自动切换。通过李雅谱诺夫指数和分叉图分析了系统的混沌特性以及系统的平衡点、分形维数、耗散性等基本特性。设计了开关函数和切换混沌系统的模拟电路,通过该电路实现了3个混沌系统的自动切换。电路实验结果与计算机仿真、李雅谱指数、分叉图分析的结果一致。

关键词: 混沌系统;开关函数;模拟电路;切换;分叉图

Abstract:

In order to generate complex chaos attractors, an automatically switching system which consists of three subsystems was constructed. Through the analog switch, the three subsystems can automatically switch in the system. The characteristics of the chaotic system and  the basic characteristics of the system, such as the equilibrium point, the fractal dimension, dissipation, were analyzed through Lyapunov index and the bifurcation diagram. The switch function and the analog circuit switching the chaotic system were designed. Through the circuit the three chaotic systems can automatically switch. Experiments results are consistent with the analysis results of computer simulation, Lyapunov exponent and bifurcation diagram.

Key words: chaotic system; switch function; analog circuit; switch; bifurcate figure
