Chaotic resonance in a fractional-order oscillator system with application to mechanical fault diagnosis

, 2021
This paper is to generalize the research on chaotic resonance (CR) towards fractional-order chaotic systems and then develop a new technique for detecting weak signals embedded in strong background noise.

Evaluation of Ability of Chaotic Resonance under Noises in Neural Systems Comprising Excitatory–Inhibitory Neurons

IEEE International Conference on Systems, Man and Cybernetics, 2021
Recent studies on stochastic resonance have been considered in various fields for engineering applications. Chaotic dynamics derive a phenomenon called chaotic resonance, which is similar to stochastic resonance.

Observation of stochastic resonance for weak periodic magnetic field signal using a chaotic system

Communications in nonlinear science & numerical simulation, 2021
Stochastic resonance, found in many natural and engineered bistable systems, refers to a physical phenomenon wherein the response of nonlinear dynamical systems to weak input signal is enhanced by the presence of noise, tuned to the optimal level ...

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

Aperiodic stochastic resonance in chaotic maps

Chaos: An Interdisciplinary Journal of Nonlinear Science, 1998
It is shown by means of numerical simulations that aperiodic stochastic resonance occurs in chaotic one-dimensional maps with various kinds of intermittency. The effect appears in the absence of external noise, as the system control parameter is varied.

Chaotic transitions in resonant asteroidal dynamics

CELESTIAL MECHANICS AND DYNAMICAL ASTRONOMY, 1996
The utilization of chaotic dynamics approaches allowed the identification of many modes of motion in resonant asteroidal dynamics. As these dynamical systems are not integrable, the motion modes are not separated and one orbit may transit from one mode to another. In some cases, as in the 3/1 resonance, these transitions may lead, in a relatively short

Stochastic resonance: A chaotic dynamics approach

Physical Review E, 1996
For a class of multistable systems it follows from qualitative results of Melnikov theory that deterministic and stochastic excitations play equivalent roles in the promotion of chaos. We use such results to suggest: (1) a method for assessing the role of the noise spectrum in enhancing the signal-to-noise ratio (SNR), the most effective spectral shape

Chaotic Third Sound Resonances

Journal of Low Temperature Physics, 2004
There are three independent phenomena that compete to determine the line shapes of third sound resonances in a circular cavity. First, anharmonic terms in the hydrodynamic equations of motion lead to the usual hysteresis on a mugti-valued response function. Second, wave coupling to vortices pinned in the film modify the resonant frequency as changes in
