Nonlinear Feedback for Control of Chaos Typeset Using Revt E X
نویسندگان
چکیده
We generalize a method of control of chaos which uses a delayed feedback governed by a nonlinear function. The method improves the region of the parameter space where control can be achieved, when compared with methods of delayed feedback that use a linear control function.

Nonlinear Diiusion Control of Spatiotemporal Chaos in the Complex Ginzburg Landau Equation Typeset Using Revt E X
The role of nonlinear diiusion terms in the stability of periodic solutions in the regime of spatio temporal chaos is studied. The stabilization of unstable plane waves in the Complex Ginzburg Landau equation in weakly chaotic regimes such as phase turbulence and spatiotemporal intermittency or in strong chaotic ones like defect turbulence is demonstrated.
متن کاملEntrainment and Communication with Dissipative Pseudorandom Dynamics Typeset Using Revt E X
We introduce a new class of dynamical systems, analog generalizations of linear feedback shift registers, that can be designed with any number of degrees of freedom, generate optimal pseudo-random noise, and exhibit nonlinear dis-sipative entrainment which can be used to decode signals in communication and measurement applications.
متن کاملEecient Determination of Nonlinear Burnett Coeecients Typeset Using Revt E X
In a previous paper Phys. Rev. A 41, 4501 (1990)], simple equilibrium expressions were obtained for nonlinear Burnett coeecients. In this paper, we devise a more eecient way of using these expressions, and show some preliminary results from a colour conductivity simulation.
متن کاملGeneration of Even and Odd Nonlinear Coherent States Typeset Using Revt E X
We show that a class of even and odd nonlinear coherent states, defined as the eigenstates of product of a nonlinear function of the number operator and the square of the boson annihilation operator, can be generated in the center-of-mass motion of a trapped and bichromatically laser-driven ion. The nonclasscial properties of the states are studied.
متن کاملTheoretical Investigation of C 60 Infrared Spectrum Typeset Using Revt E X 1
A semi-empirical model of the infrared (IR) spectrum of the C60 molecule is proposed. The weak IR-active modes seen experimentally in a C60 crystalline sample are argued to be combination modes caused by anharmonicity. The origin of these 2-mode excitations can be either mechanical (anharmonic interatomic forces) or electrical (nonlinear dipole-moment expansion in normal modes coordinates). It ...
