CONSTRUCTING CHAOTIC POLYNOMIAL MAPS

International Journal of Bifurcation and Chaos, 2009
This paper studies the construction of one-dimensional real chaotic polynomial maps. Given an arbitrary nonzero polynomial of degree m (≥ 0), two methods are derived for constructing chaotic polynomial maps of degree m + 2 by simply multiplying the given polynomial with suitably designed quadratic polynomials.

Lissajous chaotic map

International Conference on Neural Networks and Signal Processing, 2003. Proceedings of the 2003, 2003
Chaos has been widely applied in the fields including pattern recognition, data compression, and autocontrol. It has been attached great importance to for its special use in secrete communication systems. In this paper, we based on the explicit function, which was said to be a random data generator, and proposed a new kind of map called Lissajous ...

CHAOTIC CONTROL OF LOGISTIC MAP

Modern Physics Letters B, 2008
With the occasional feedback method, the chaotic logistic map is stabilized at an unstable low-periodic orbit. In our method, the qualified feedback coefficient can be obtained through calculation instead of through simulation. Besides, the bifurcation control of the logistic map is studied, and a new scheme is proposed to change the parameter value of

Noise-resistant chaotic maps

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2002
Synchronized chaotic systems are highly vulnerable to noise added to the synchronizing signal. It was previously shown that chaotic circuits could be built that were less sensitive to this type of noise. In this work, simple chaotic maps are demonstrated that are also less sensitive to added noise.

MEHRAB MAPS: ONE-DIMENSIONAL PIECEWISE NONLINEAR CHAOTIC MAPS

International Journal of Bifurcation and Chaos, 2012
In this paper, we propose a new one-dimensional, two-segmental nonlinear map by combining tent, triangle and parabola curve functions. We call the proposed map, Mehrab map since its return maps shape is similar to an altar (which we call it "Mehrab").

Regular approximations to chaotic maps

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2008
We construct regular analytic approximations to partly chaotic maps on a two-dimensional torus—the Standard Map in particular. Possible extensions are discussed.
