| Abstract: | A two-dimensions discrete chaotic map with rational fractionation is constructed by nonlinear characteristics tools. Then, its dynamic behaviors is studied with the largest Lyapunov exponents spectrum and global bifurcation diagram. Finally, the chaotic attractor can be controlled effectively and fleetly by nonlinear contraction maps, which are composed of improved wavelet functions form. The utility and validity of this new method is validated with theory analysis and numerical simulation. |
