Un Método de Perturbaciones Paramétricas para Controlar el Circuito de Chua

Abstract

Chaos control has been an expanding research area over the last decade, therefore a great amount of techniques have been developed for controlling or suppressing chaos. Some of the most popular techniques are the so-called parametric perturbation methods, which are derived from the original OGY method (1). These techniques use an accessible system's parameter for being changed in order to stabilize one of the system's Unstable Periodic Orbits. In this paper we report the application of an extension from the OGY approach to control chaos in Chua's circuit. This extension consists in using a First Return Map instead of a Poincare Map for describingthe system's dynamics in the neighborhoodof an Unstable Periodic Orbit.
