Delay‐dependent small‐signal stability analysis of inverter‐based islanded microgrids

IET Smart Grid, Volume 8, Issue 1, January/December 2025.
This paper investigates the effect of communication delays on the operational stability of Microgrids (MGs) with GFM and GFL inverters in islanded mode. An evaluation scheme is developed for the small‐signal stability of inverter‐based MGs. Abstract The stability of an inverter‐based hierarchical microgrid is challenged by inverter controls, network ...

On the stability of impulsive functional differential equations with infinite delays [PDF]

, 2015
In this paper, the stability problem of impulsive functional differential equations with infinite delays is considered. By using Lyapunov functions and the Razumikhin technique, some new theorems on the uniform stability and uniform asymptotic stability ...

Stability Analysis for Systems with Time-Varying Delay: Trajectory Based Approach [PDF]

, 2015
International audienceRecent work by Mazenc and Malisoff provided a trajectory-based approach to proving stability of time-varying systems with time-varying delay. It uses a contraction lemma, instead of Lyapunov-Krasovskii or Razumikhin functions. Here,

Leveraging an LMI‐Based Approach for Finite‐Time Control of Nonlinear Systems in the Presence of State‐Dependent Delays and Parametric Uncertainties

Complexity, Volume 2025, Issue 1, 2025.
In recent years, the study of finite‐time stability (FTS) and finite‐time control (FTC) of time‐delay systems has attracted significant attention from researchers. This article investigates the problems of FTS and FTC for nonlinear systems in the presence of state‐dependent delays and parametric uncertainties.

The Stability of Stationary Equilibria of Mean Field Games With Finite State and Action Space

Journal of Function Spaces, Volume 2025, Issue 1, 2025.
The aim of this paper is to study some new stability results on the essential component and generic uniqueness of stationary equilibria for mean field games with finite state and action space (briefly, FSASMFG). A group of FSASMFGs comprises a dense residual subset such that every point of stationary mean field equilibrium (briefly, SMFE) is essential.

Impulsive Control for the Synchronization of Chaotic Systems with Time Delay

Abstract and Applied Analysis, 2012
This paper considers impulsive control for the synchronization of chaotic systems with time delays. Based on the Lyapunov functions and the Razumikhin technique, some new synchronization criteria with an exponential convergence rate are derived.

Mean Square Polynomial Stability of Numerical Solutions to a Class of Stochastic Differential Equations

, 2014
The exponential stability of numerical methods to stochastic differential equations (SDEs) has been widely studied. In contrast, there are relatively few works on polynomial stability of numerical methods.

A robust predictive control scheme for uncertain continuous‐time delayed systems under actuator saturation

IET Control Theory &Applications, Volume 18, Issue 14, Page 1779-1790, September 2024.
A predictive controller is robustly designed in uncertain delayed models with saturated input. A state‐feedback control structure with unknown gains is considered as the compensator to overcome the difficulties. In the uncertain delayed systems with constraints, relying on linear matrix inequality, an optimization issue will be discovered to specify ...

Reduction Model Approach for Systems with a Time-Varying Delay [PDF]

, 2015
International audienceWe provide a reduction model approach for achieving global exponential stabilization of linear systems with a time-varying pointwise delay in the input. We allow the delay to be discontinuous and uncertain.
