The Stochastic Resonance Phenomenon of Different Noises in Underdamped Bistable System

Advances in Mathematical Physics, 2021
In this paper, the stochastic resonance (SR) phenomenon of four kinds of noises (the white noise, the harmonic noise, the asymmetric dichotomous noise, and the Lévy noise) in underdamped bistable systems is studied.

On square-wave-driven stochastic resonance for energy harvesting in a bistable system

AIP Advances, 2014
Stochastic resonance is a physical phenomenon through which the throughput of energy within an oscillator excited by a stochastic source can be boosted by adding a small modulating excitation.

Actuator Weak Fault Diagnosis in Autonomous Underwater Vehicle Based on Tri-Stable Stochastic Resonance

Applied Sciences, 2020
The autonomous underwater vehicle (AUV) is mainly used in the development and exploration of the ocean. As an important module of the AUV, the actuator plays an important role in the normal execution of the AUV.

Nonstationary stochastic resonance [PDF]

Physical Review E, 1998
It is by now established that, remarkably, the addition of noise to a nonlinear system may sometimes facilitate, rather than hamper the detection of weak signals. This phenomenon, usually referred to as stochastic resonance, was originally associated with strictly periodic signals, but it was eventually shown to occur for stationary aperiodic signals ...

Stochastic resonance of two coupled fractional harmonic oscillators in Jerk equation

Results in Physics, 2023
The stochastic resonance (SR) phenomenon in two coupled fractional harmonic oscillators with inherent frequency, employing the Jerk equation under the influence of multiplicative dichotomous noise and an applied periodic force have been investigated in ...

Power System Signal-Detection Method Based on the Accelerated Unsaturated Stochastic Resonance Principle

Applied Sciences
The classical bistable stochastic resonance algorithm has an inherent output saturation defect that restricts the amplitude of the output signal. This paper examines the causes of this phenomenon and its negative impact on the detection of weak signals ...
