| 摘 要： | 分析了一个二维离散超混沌系统吸引子的存在性,通过数值模拟得到系统随参数变化的分岔图,Lyapunov指数谱和吸引子图像,说明了系统由周期运动到超混沌运动的转迁过程。利用X|X|控制方法,系统的超混沌行为可以有效的控制并得到稳定的周期轨道,数值仿真表明了这个方法的可行性和有效性。

| Abstract: | In the paper,the existence of the attractor in a two-dimensional hyperchaotic discrete system is studied.The bifurcation diagram and the corresponding Lyapunov exponent and attractors are got by means of numerical simulation to show its transition from periodic state to hyperchaotic state.By using the method in the form of X|X|,the hyperchaotic motions of system can be controlled effectively and we obtain the steady periodic state.Numerical simulations show the applicability and effectiveness of the method. |
