广域混沌系统的切换及同步控制
Switching and synchronization control of wide-area chaotic systems
摘要
Abstract
A new class of three-dimensional switched chaotic systems has been proposed based on the T system.By changing the nonlinear term of T system and adding the state feedback term,eight subsystems that have only two nonlinear terms with free switching were constructed.It is found that some systems have symmetrical characteristics by analyzing the subsystem phase diagram.The dynamics of the subsystem was studied to determine the chaotic state of the system and the type of equilibrium point,while the influence of the system parameters on the chaotic characteristics of the subsystem was obtained.It was found that there was a large range of chaos parameter in multiple subsystems.Multisim simulation software was employed to construct a switching circuit for eight subsystems,and the system selection switch was utilized to validate the practicality of the system circuit.An adaptive synchronization controller was designed to realize the synchronization control of the subsystems,and the effectiveness of synchronization was verified by simulation.These switchable chaotic systems exhibit significant application value in practical fields such as image encryption and biomedicine.关键词
