DYNAMICS OF THE NONAUTONOMOUS CHUA'S CIRCUIT

Abstract

In this paper, we investigate via physical experiments and computer simulations the response of Chua's circuit under periodic external forcing. The amplitude and frequency of the external forcing form two additional control parameters, and we present bifurcation diagrams on the plane of these two parameters. We investigate the behavior of Chua's circuit due to external forcing when the unforced circuit is in various dynamical regimes. We finally compare our results with those obtained from a nonautonomous oscillator with an inertial nonlinearity.
