摘要
A new four-dimensional memristive chaotic circuit is proposed by adding a smooth active memristor to the modified Chua's circuit.The appropriate parameters of the memristor are selected and its characteristics are verified.The dissipativity,equilibrium point set and stability of this new memristive chaotic circuit are analyzed theoretically.The dynamic characteristics of the chaotic system are presented by means of phase-diagram,Lyapunov exponent and bifurcation diagram.Finally,the circuit model of the memristive chaotic system is designed using Multism simulation software.The experimental and simulation results are consistent that proves the feasibility of the system.
