In this letter a new chaotic system is discussed. Some basic dynamic properties, such as symmetry, dissipation, continuous spectrum and chaotic behaviors of the butterfly attractor are studied. Furthermore, period-doubling bifurcations in a system with definite parameters has been investigated. 相似文献

一类统一混沌系统的追踪控制与同步 总被引:10,自引:0,他引:10
对一类统一混沌系统进行控制,设计出一种含参控制器,使受控系统追踪任意给定的一维参考信号和三维参考信号,利用Lyapunov方法证明在此控制器作用下该系统按指数速率收敛到参考信号。同时研究了此受控统一混沌系统的自同步及异结构同步问题。利用Chen′s混沌系统进行数值仿真,其结果说明了此控制器设计方法的有效性。 相似文献

This paper discusses the local and global center of the generalized Lienard system, gives two theorems which extend and improve the relative results of [1]-[3]. Moreover the lemmas in this paper are also useful to the study for the oscillation, stability and the existence of limit cycles of the generalized Lienard system. 相似文献
