A novel parametrically controlled multi-scroll chaotic attractor along with electronic circuit design

Abstract

We propose a novel multi-scroll chaotic system captured through the Chua’s circuit. The novelty of our proposed multi-scroll system roots on the number of scrolls to be controlled by the parameters instead of changing the discontinuous functions repeatedly reported in the literature. We thoroughly investigate dynamical characteristics of the system using powerful tools of the nonlinear dynamic analysis including finite-time local Lyapunov exponents and bifurcation diagram. The practical feasibility of the proposed multi-scroll system is revealed through its electronic realization with off-the-shelf components.
