摘要

混沌动力学系统具有初始条件的极端敏感性

当参数空间发生漂移时

系统的解空间将出现很大的变化.以Feigenbaun映射为例

分析了参数引起的分叉行为

提出利用混沌周期解提高测试系统灵敏度的方案.调整参数使测试系统工作在周期解的区域

根据参数敏感激发混沌系统周期数变化

设计了测量算法改善测量的精度和灵敏度

对混沌系统的抗干扰性进行了分析.

Abstract

The chaotic system will bifurcate when the system parameters change a little.If the measured signal was put to the chaotic system

it would be get the stable state

period states and chaotic states.In the article

controlling the system work at the period states makes the states changes with the signal

A chaotic circuit has been added to the measurement system to improve the delicacy.The measurement delicacy was analyzed.The results of chaotic system immuned with the noises were given.
