基于双曲函数的双忆阻器混沌电路多稳态特性分析
Multistability Analysis of a Dual-Memristor Circuit Based on Hyperbolic Function
摘要
Abstract
A novel magnetron memristor model based on the hyperbolic sine function is proposed.And then,a new type of five-dimensional dual-memristor chaotic circuit is built by replacing the nonlinear resistance in the Chua's system with the magnetron memristor model.It is found that the dual-memristor system has the equilibrium point set.In addition,the numerical simulation of the memristive system is carried out by selecting the different initial values of the system and the multistribution characteristics of the fifth-order chaotic system are analyzed in detail by using the bifurcation diagram and Lyapunov exponent spectrum.The results show that the dual-memristive chaotic circuit is different from the dynamic behav-ior of the chaotic system.The motion trajectory of system depends not only on the circuit parameters but also on the initial state of the circuit,resulting in the coexistence of different periodic motions and different chaotic attractors with different to-pologies.关键词
