Nonlinearly Activated IEZNN Model for Solving Time-Varying Sylvester Equation

open access: yesIEEE Access, 2022
Zeroing neural network (ZNN) is an effective method to calculate time-varying problems. However, the ZNN and its extensions separately addressed the robustness and the convergence.

Parareal Convergence for Oscillatory PDEs with Finite Time-Scale Separation [PDF]

open access: yesSIAM Journal on Scientific Computing, 2019
A variant of the Parareal method for highly oscillatory systems of PDEs was proposed by Haut and Wingate (2014). In that work they proved superlinear conver- gence of the method in the limit of infinite time scale separation. Their coarse solver features a coordinate transformation and a fast-wave averag- ing method inspired by analysis of multiple ...

Distributed Finite-Time Secondary Frequency and Voltage Restoration Control Scheme of an Islanded AC Microgrid

open access: yesEnergies, 2021
To solve the problems of frequency and voltage deviation caused by the droop control while meeting the requirements of rapid response, a distributed finite-time secondary control scheme is presented.

On The Convergence of Euler Discretization of Finite-Time Convergent Gradient Flows

open access: yes, 2020
In this study, we investigate the performance of two novel first-order optimization algorithms, namely the rescaled-gradient flow (RGF) and the signed-gradient flow (SGF). These algorithms are derived from the forward Euler discretization of finite-time convergent flows, comprised of non-Lipschitz dynamical systems, which locally converge to the minima

A robust finite-time convergent hybrid observer for linear systems [PDF]

open access: yes52nd IEEE Conference on Decision and Control, 2013
Motivated by the design of observers with good performance and robustness to measurement noise, the problem of estimating the state of a linear time-invariant system in finite time and with robustness to a class of measurement noise is considered. Using a hybrid systems framework, a hybrid observer producing an estimate that converges to the plant ...

Finite element approximation of a nonlinear cross-diffusion population model [PDF]

open access: yes, 2003
We consider a fully discrete finite element approximation of the nonlinear cross-diffusion population model: Find u i, the population of the ith species, i = 1 and 2, such that ∂ui ∂t −Δ [ ci ui + ai u2i + ui uj] − bi ∇.

Adaptive Control of a Constrained First Order Sliding Mode for Visual Formation Convergence Applications

open access: yesIEEE Access, 2023
Most existing solutions that guarantee finite-time convergence of a constrained first-order sliding mode either assume that the structure of the perturbation is known apriori, or the perturbation and its derivative are bounded by unknown constants ...

Variational Time Integrators in Computational Solid Mechanics [PDF]

open access: yes, 2003
This thesis develops the theory and implementation of variational integrators for computational solid mechanics problems, and to some extent, for fluid mechanics problems as well.

Single-Bit Consensus With Finite-Time Convergence: Theory and Applications [PDF]

open access: yesIEEE Transactions on Aerospace and Electronic Systems, 2020
In this brief paper, a new consensus protocol based on the sign of innovations is proposed. Based on this protocol each agent only requires single-bit of information about its relative state to its neighboring agents. This is significant in real-time applications, since it requires less computation and/or communication load on agents.
