| 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. |
