Finite-Time Synchronization of Chaotic Complex Networks with Stochastic Disturbance

open access: yesEntropy, 2014
This paper is concerned with the problem of finite-time synchronization in complex networks with stochastic noise perturbations. By using a novel finite-time ℒ -operator differential inequality and other inequality techniques, some novel sufficient ...

Predefined-Time Control of Full-Scale 4D Model of Permanent-Magnet Synchronous Motor with Deterministic Disturbances and Stochastic Noises

open access: yesActuators, 2021
This paper presents a predefined-time convergent robust control algorithm that allows the control designer to set the convergence time in advance, independently of initial conditions, deterministic disturbances, and stochastic noises.

Stochastic approximation with dependent disturbances—I

open access: yesComputers & Mathematics with Applications, 1987
The author studies a generalization of the Robbins-Monro procedure when disturbances satisfy a law of large numbers (strong or week) and proves convergence of this stochastic approximation procedure (accordingly, almost surely or in probability). The proofs of results are based on properties of deterministic iterative procedures for seeking zeros of ...

Identification of a Stochastic Dynamic Model for Aircraft Flight Attitude Based on Measured Data

open access: yesInternational Journal of Aerospace Engineering, 2023
Stochastic disturbances are everywhere. The influence of stochastic factors on the modeling and simulation of aircraft flight dynamics should be considered.

Adaptive Robust Control for a Class of Stochastic Nonlinear Uncertain Systems

open access: yesIEEE Access, 2020
This paper is concerned with the control design for a class of stochastic nonlinear systems. Three uncertainties are considered; that is, nonlinear parameter uncertainty, matched uncertainty and stochastic disturbance.

A lattice grain model of hillslope evolution [PDF]

open access: yesEarth Surface Dynamics, 2018
This paper describes and explores a new continuous-time stochastic cellular automaton model of hillslope evolution. The Grain Hill model provides a computational framework with which to study slope forms that arise from stochastic disturbance and rock

On the Stochastic Dynamics of a Social Epidemics Model

open access: yesDiscrete Dynamics in Nature and Society, 2017
Alcohol abuse is a major social problem, which has caused a lot of damages or hidden dangers to the individual and the society. In this paper, with random factors of alcoholism considered in mortality rate of compartment populations, we formulate a ...

Stochastic and deterministic assembly processes of microbial communities in relation to natural attenuation of black stains in Lascaux Cave

open access: yesmSystems
Community assembly processes are complex and understanding them represents a challenge in microbial ecology. Here, we used Lascaux Cave as a stable, confined environment to quantify the importance of stochastic vs deterministic processes during microbial

Mean Square Exponential Stability of Stochastic Complex-Valued Neural Networks with Mixed Delays

open access: yesComplexity, 2019
This paper investigates the mean square exponential stability problem of a class of complex-valued neural networks with stochastic disturbance and mixed delays including both time-varying delays and continuously distributed delays.
