Abstract

A chaos feedback system including a chaotic system capable of analyzing whether an input signal is obtained from a noise or from a meaningful information by analyzing qualitative features of the strange attractor and feed the analyzed result back to the chaotic system so that the chaotic system outputs a desired state. The chaos feedback system includes a chaotic system for deriving a stable state solution from input states, the chaotic system having a strange attractor obtained from the stable state solution, a chaos processor for outputting a correlation dimension to analyze a quantitative feature from a state value of the strange attractor in real time, and a chaos feedback controller part for feeding a result outputted from the chaos processor back to the chaotic system so that the chaotic system outputs a desired state value.

Claims

a chaotic system for deriving a stable state solution from input states, said chaotic system having a strange attractor obtained from said stable state solution;

chaos processor means for outputting a correlation dimension to analyze a quantitative feature from a state value of said strange attractor; and

chaos feedback controller means for feeding a result outputted from said chaos processor means back to the chaotic system so that the chaotic system outputs a desired state value;

said chaos processor means comprising a plurality of chaos processors for deriving correlation dimensions for state values inputted with different embedding dimensions and different delay times, respectively.

2. A chaos feedback system in accordance with claim 1, wherein said chaos feedback controller means comprises a plurality of feedback control parts for receiving said correlation dimensions from said chaos processors, respectively, so that said chaotic system outputs a desired state value.

3.
