研究了两种周期脉冲作用下Logistic映射的复杂动力学行为.随着参数的变化,该系统产生平衡解、周期解、混沌等现象,且该系统可经级联倍周期分岔到达混沌.通过构造Poincar映射,对周期脉冲作用下Logistic映射进行了分岔分析.最后基于Floquet理论揭示了该系统周期解的分岔机理.
The complex dynamics of the Logistic map via two types of periodic impulsive forces is investigated in this paper. With the parameter varying, the system produces the phenomenon such as equilibrium solutions, periodic solutions, and chaotic solutions. Furthermore the system can evolve into chaos by a cascading of period-doubling bifurcations. The Poincar6 map of the Logistic map via periodic impulsive force is constructed and its bifurcation is analyzed. Finally, the Floquet theory is used to explore the bifurcation mechanism for the periodic solutions.
