Sustained Chaos State and Coexisting Attractors in a Memristive System

In this paper, a new memristive model is proposed and realized by Matlab software and Multisim software. Based the memristor, a memristive chaotic system is designed. The chaotic system has abundant dynamic characteristics, including coexisting attractors and sustained chaotic state. The coexisting bifurcation diagrams connected with coexisting attractors are discovered by varying the system parameters. The corresponding dynamic behaviors are analyzed by Lyapunov exponents, bifurcation diagrams and phase portraits. The chaotic circuit is realized by Multisim circuit simulations, and the simulation results are consistent with numerical simulations.
