Characterizing the Response of Chaotic Systems

Physical Review Letters, 2010
We characterize the response of a chaotic system by investigating ensembles of, rather than single, trajectories. Time-periodic stimulations are experimentally and numerically investigated. This approach allows detecting and characterizing a broad class of coherent phenomena that go beyond generalized and phase synchronization.

OPTIMAL CONTROL OF CHAOTIC SYSTEMS

International Journal of Bifurcation and Chaos, 2001
The problem of controlling a chaotic system is treated from a long term statistical basis. Unlike the OGY targeting method that exploits individual unstable orbits, this approach is concerned with targeting the density function of an invariant probability measure. Given a point transformation T, possessing a density function f, we choose [Formula: see

IDENTICAL SYNCHRONIZATION OF CHAOTIC SYSTEMS

International Journal of Bifurcation and Chaos, 2006
We consider the problem of identical synchronization (IS) of chaotic systems in two cases: (i) system uncertainty exists in the drive system, and (ii) output uncertainty exists in the drive system. No matter which case it is, the IS problem can be resolved via the combination of unknown input observers (UIOs) and the linear matrix inequalities (LMIs).

IMPULSIVE CONTROL OF CHAOTIC SYSTEM

International Journal of Bifurcation and Chaos, 2002
This paper studies an impulsive control problem. By utilizing the method of Lyapunov functions, a set of impulsive stabilization criteria are established. These results are then applied to the Lorenz system. It is shown that by using impulsive feedback control, all the solutions of the Lorenz system will converge to an equilibrium point.

ANALYSIS OF A QUANTIZED CHAOTIC SYSTEM

International Journal of Bifurcation and Chaos, 2002
We consider quantized chaotic dynamics for a spiking oscillator with two periodic inputs. As the first input is applied, the oscillator generates various periodic and chaotic pulse-trains governed by a pulse position map. As the second input is added, the oscillator produces pulse positions restricted on a lattice, and the pulse position map is ...

PSEUDO-DETERMINISTIC CHAOTIC SYSTEMS

International Journal of Bifurcation and Chaos, 2003
We call a chaotic dynamical system pseudo-deterministic when it does not produce numerical, or pseudo-trajectories that stay close, or shadow chaotic true trajectories, even though the model equations are strictly deterministic. In this case, single chaotic trajectories may not be meaningful, and only statistical predictions, at best, could be drawn on

Resonances of Chaotic Dynamical Systems

Physical Review Letters, 1986
We present analytic properties of the power spectrum for a class of chaotic dynamical systems (Axiom-A systems). The power spectrum is meromorphic in a strip; the position of the poles (resonances) depends on the system considered, but only their residues depend on the observable monitored. In relation with these results we also discuss the exponential

Synthesis of chaotic systems

Kybernetika, 1994
The authors propose an approach to construct a chaotic system by the synthesis of a linear dissipative single-input single-output system and a nonlinear static output feedback. An example constructed in this way is illustrated by computation.

Chaotic Behavior in Excitable Systems

Annals of the New York Academy of Sciences, 1990
This paper has dealt with biophysically accurate, or plausible, excitation systems. These are obtained from experiments, and so are complicated, often of high order, and are continually being updated by new experimental results. This is especially true for the excitation equations that represent cardiac tissue.

Chaotic Continua in Chaotic Dynamical Systems

2021
In this article, for any graph G we define a new notion of “free tracing property by free G-chains” on G-like continua and we show that a positive topological entropy homeomorphism f of a G-like continuum X admits a Cantor set Z in X such that any sequence \((z_1,z_2,...,z_n)\) of points in Z is an IE-tuple of f, Z has the free tracing property by free
