吸引子共存的四维多稳态混沌系统及同步电路
Four-dimensional multistable chaotic systems and synchronous circuits with attractor coexistence
摘要
Abstract
A four-dimensional chaotic systems with multi-winged attractors is designed,which can change the attractor structure four wings to two wings by changing the system parameters.The phase diagram,Lyapunov exponential spectrum,bifurcation diagram and complexity methods are used to verify the dynamic characteristics of the system.The results show that,by changing the system parameters and choosing different initial values,the system can exhibit the coexistence of attractors with opposite polarity but similar structure.Multisim simulation software is used for the circuit simulation,and it is found that the numerical analysis and simulation results are consistent,thus verifying the realizability of the system.The linear feedback synchronization method is used for the synchronous control of the system,and the simulation of synchronization circuit is realized successfully.The master-slave system can realize the synchronization in a very short time,and the synchronization effect is good,which can be widely used in the field of secure communication.关键词
