摘要:

为了探究非线性系统中的超混沌现象,在超混沌Tang系统的基础上构建了一个新型超混沌系统。根据混沌动力系统的Lyapunov稳定性理论、定性理论和分岔理论研究了新的超混沌系统的混沌动力学特性,包括耗散性、平衡点及其局部稳定性、部分参数变化时的Lyapunov指数谱和分岔图等。通过引进广义Lyapunov函数,从数学理论上证明了新超混沌系统存在全局指数吸引集。利用全局指数吸引集的结果证明了用线性反馈控制方法使两个超混沌Tang系统达到全局指数同步,随后也给出了利用非线性反馈控制达到全局指数同步的控制器设计方法。最后通过数值仿真,证实了两种反馈控制方法都能达到全局指数同步,并对比了两种控制方法的优点。

Abstract:

In order to investigate the hyperchaos phenomena in nonlinear systems, a new hyperchaotic system based on the hyperchaotic Tang system is constructed. Based on the Lyapunov stability theory, qualitative theory and bifurcation theory, the dynamical characteristics of this new hyperchaotic systems are studied, including dissipation, equilibrium point and its local stability, Lyapunov exponential spectrum and bifurcation diagram of some \mbox{parameters} change. By introducing the generalized Lyapunov function, it is proved that there exists the global exponential attractive set for the new hyperchaotic system. The global exponential synchronization of two hyperchaotic Tang systems is studied by using the global exponential attraction set and a linear controller is given to achieve global exponential synchronization. Then, a nonlinear feedback controller is presented to achieve global exponential synchronization. Finally, through numerical simulation, it is proved that both feedback control methods can achieve global exponential synchronization and the advantages of the two methods are compared.

Key words: hyperchaotic system, stability, global attraction domain, bifurcation, global exponential synchronization
