摘要
混沌系统的一个重要特性是初值敏感性和参数敏感性。初值敏感性是指混沌系统中初值的微小变化就会导致混沌轨道的很大变化。本系统反过来分析轨道的变化,便可测出输入数值的变化。先利用混沌充放电电路将输入模拟量采集成一组二进制序列,然后对其进行分析,得到输入量的准确估计值。本系统具有电路设计简单,成本低,分辨率高的特点。
An important property of chaos system is initial sensitivity and parameter sensitivity. Chaos initial value sensitivity refers to small changes of initial value can lead to great changes of chaotic orbit. It is analyzed that the changes in orbit can detect the changes in input value. Chaos circuit charge an analog input into a group of binary sequences collection, then analyze and get the accurate measuring inputs. This system has characteristics of simple design, low cost and high resolution.
