Parameter Characteristics of the Hidden Attractor in an Improved Sprott-A System
摘要/Abstract
将一非线性函数引入到系统中得到改进型的Sprott-A模型，通过选取非线性函数为正弦函数，可以得到多滚动隐藏吸引子，通过系统相轨道、时间演化及Lyapunov指数的计算，分析了系统的动力学特性，研究了系统参数对滚动隐藏吸引子变化的影响.最后，使用Multisim软件设计了系统的电路图，得到的波形图与对应的相轨迹图相同.
In this paper,a nonlinear function was introduced into the system to obtain an improved Sprott-A model.By selecting the nonlinear function as the sine function,we can get the multi-scroll hidden attractor.The dynamic characteristics of the system are analyzed by calculating the phase orbit,time evolution and Lyapunov index,and the influence of system parameters on the change of scroll-hiding attractor is studied.Finally,an electronic circuit of the system is implemented in Multisim,and the results of electronic circuit are consistent with that of the corresponding phase orbit.
