1. A chaos feedback system comprising: 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.
