- Abstract:
- A new Chua circuit based on a novel third order memristor is proposed,in the light of Kirchhoff voltage law, Kirchhoff current law and the characteristics of each component. The phase trajectory diagram,Lyapunov exponent diagram,Poincare cross section diagram and bifurcation diagram are obtained by building and utilizing the mathematical model of the new Chua circuit .The nonlinear dynamic characteristics of the Chua circuit based on a novel third order memristor is analyzed,and the results show that the new Chua circuit exhibit more complex and abundant chaotic phenomena and nonlinear dynamic behaviors,provide references for the research of chaotic circuit and image encryption.
