近似时滞超混沌系统的动力学特性分析
Dynamics Analysis on Hyperchaotic System with Approximate Time-delay State Feedback
【摘要】 .为揭示近似时滞超混沌系统的复杂动力学特性,计算了该系统产生的超混沌吸引子的混沌特征量,包括Lyapunov指数、关联维数、Kolmogorov墒、频谱和Poincare截面,并将之与经典的Lorenz吸引子进行了比较.从数值实验方面证明近似时滞超混沌吸引子比经典的Lorenz吸引子具有复杂的动力学特性.
【Abstract】 In order to reveal the complicated dynamics of the hyperchaotic system with approximate time-delay state feedback,the chaotic characteristics of the attractors,including Lyapunov exponents,correlation dimension,Kolmogorov entropy,frequency spectrum and Poincare section,are figured out and compared with that of Lorenz attractor.Numerical simulation experiment shows that the hyperchaotic attractor with approximate time-delay state feedback has more complicated dynamics property than Lorenz attractor.
