A Study of Identification and Control in a Real Implemetation of Chua'S Circuit

Abstract

This paper presents some results of a study of identification and control of chaos in a real electronic circuit. In all experiment we used an op-amp implementation of Chua's circuit. An application specific software package has been developed. This package cosists of programs for handling automatic measurements in the electronic system, characterisation of the system on the basis of measured experimental time series (identification), generation of the control signals for stabilisation of chosen periodic state. The software is fully interactive - the user takes the decisions at each step of the procedure (eg. length of the measured interval, choice of orbits to compute, goal of the control etc
