摘要
在Chen氏三维混沌系统的基础上构造了一个四维系统,对系统进行了动力学理论分析和计算机数值仿真研究。发现构造出的系统可以随系统参数的变化而产生周期、准周期、混沌和超混沌运动。详细分析了四维系统的特性,设计了超混沌系统的自同步控制器和异结构同步控制器,并通过计算机数值仿真证实了此同步控制方法的有效性。
In this paper, a four-dimensional system has been constructed basing on the new three-di- mensional chaotic of systems in reference which is constructed to the Chen system by the author, and the dynamics of the system has been carried on the theoretical analysis and numerical simulation. Through the study, one can find that the four-dimesional system has periodic quasi-periodie chaotic and hyper chaotic behaviours with the charge of systerm parameters. On this basis, via existing literature method, the feature of four-dimensional system is analyzed, and a four-dimensional system of adaptive controller and controller structure are designed in this paper. Through the theoretical analysis and research, The effectiveness of the proposed controller gets proved which has been put forward in this pa- per. Through designing of the synchronization controller, the synchronization of the system is completed, and the simulation of the controller is verified through numerical simulation.
