一个新的非线性系统及其超混沌控制
A novel nonlinear system and its hyperchaotic control
摘要
Abstract
In order to generate complex hyperchaotic attractor,a new four-dimensinal nonlinear system based on the classic Lii system is built via deformation and introducing nonlinear state feedback controler. Its basic dynamical properties are briefly investigated via the attractors at edvia the atlractors, the bifurcation diagram. Lyapunov exponent spectrum and fractal dimension. The new system displays periodic, quasi-periodic, chaotic and hyperchaotic when the introduced parameter is changed. The hyperchaotic motion of the system is suppressed using the method of single variable proportion and differential feedback. Theoretical analysis and computer simulations results show the feasibility and effectiveness of the method.关键词
