A Memristor-Based Chaotic System with Bifurcation Analysis

Abstract

This paper proposes and investigates a memristor-based chaotic system by incorporating an HP TiO2 memristor into the canonical Chen's chaotic system. More precisely, a charge-controlled memristor model with some appropriate boundary conditions is introduced. The relationship between the electric charge and the flux passing through the memristor is formulated and then employed as a nonlinear term in the constructed chaotic system. The rich dynamical behaviors of the memristor-based system are demonstrated by calculating the Lyapunov exponent spectrum and Lyapunov dimension, observing the chaotic attractors, analyzing the bifurcations.
