A new hyperchaotic system and its adaptive tracking control

摘要: 通过在一个三维混沌系统中加入状态反馈控制器,构造出一个新的四维超混沌系统.分析表明,随着不同参数变化该系统呈现周期、复杂周期、准周期、混沌及超混沌运动.同时设计出模拟电子电路对该超混沌系统进行了实验验证.最后,设计了一个自适应追踪控制器,实现了其对各种不同参考信号的单变量追踪控制.

Abstract: In this paper,a four-dimensional hyperchaotic system is constructed by adding a state feedback controller into a chaotic system. Numerical simulations and theoretical analysis show that this four-dimensional system will take on periodic.complex periodic, quasi-periodic chaotic hyperchaotic dynamical behaviours as parameters vary.Moreover,an electronic circuit diagram is designed for demonstrating the existence of the hyperchaos.Finally,an adaptive tracking controller is proposed to acquire adaptive tracking control for this hyperchaotic system.
