Generalised theory on asymptotic stability and boundedness of stochastic functional differential equations [PDF]

open access: yes, 2011
Asymptotic stability and boundedness have been two of most popular topics in the study of stochastic functional differential equations (SFDEs) (see e.g. Appleby and Reynolds (2008), Appleby and Rodkina (2009), Basin and Rodkina (2008), Khasminskii (1980),

Ultimate boundedness of droop controlled microgrids with secondary loops [PDF]

open access: yes2014 4th Australian Control Conference (AUCC), 2014
In this paper we study theoretical properties of inverter-based microgrids controlled via primary and secondary loops. Stability of these microgrids has been the subject of a number of recent studies. Conventional approaches based on standard hierarchical control rely on time-scale separation between primary and secondary control loops to show local ...

New result on the ultimate boundedness of solutions of certain third-order vector differential equations [PDF]

open access: yes, 1983
summary:Sufficient conditions are established for ultimate boundedness of solutions of certain nonlinear vector differential equations of third-order. Our result improves on Tunc’s [C.

Aggregation–decomposition and equi-ultimate boundedness [PDF]

open access: yesThe Journal of the Australian Mathematical Society. Series B. Applied Mathematics, 1975
AbstractThe aggregation–decomposition method is used to derive a sufficient condition for the equi-ultimate boundedness of large-scale systems governed by nonlinear ordinary differential equations.

Uniformly ultimate boundedness of solutions for some 3-dimensional systems [PDF]

open access: yes, 2004
For some 3-dimensional system of electrial circuits, the uniformly ultimate boundedness of solutions is proved, and consequently existing unstable manifolds around equilibrium points is ...

A stochastic three-species food web model with Lévy jumps

open access: yesJournal of Hebei University of Science and Technology, 2019
For a stochastic three-species food web model with double parameters perturbation and Lévy jumps, we give the existence and uniqueness of global positive solution,which is beneficial to further study its dynamic properties. Then, by constructing Lyapunov

Ultimate Boundedness of Solutions for Certain Third Order Nonlinear Differential Equations [PDF]

open access: yes, 2016
We investigate in this paper, the ultimate boundedness of solutions for certain special class of third order nonlinear differential equations. Using suitable complete Lyapunov function, we obtain the criteria for the ultimate boundedness of solutions for

Backstepping-Based Quasi-Sliding Mode Control and Observation for Electric Vehicle Systems: A Solution to Unmatched Load and Road Perturbations

open access: yesWorld Electric Vehicle Journal
The direct current (DC) motor is the core part of an electrical vehicle (EV). The unmatched perturbation of load torque is a challenging problem in the control of an EV system driven by a DC motor and hence a deep control concern is required.

Qualitative Study of a 4D Chaos Financial System

open access: yesComplexity, 2018
Some dynamics of a new 4D chaotic system describing the dynamical behavior of the finance are considered. Ultimate boundedness and global attraction domain are obtained according to Lyapunov stability theory.
