Inexact Newton–Kantorovich Methods for Constrained Nonlinear Model Predictive Control

open access: yesIEEE Transactions on Automatic Control, 2019
In this paper, we consider Newton–Kantorovich type methods for solving control-constrained optimal control problems that appear in model predictive control. Conditions for convergence are established for an inexact version of the Newton–Kantorovich method applied to variational inequalities. Based on these results, two groups of algorithms are proposed

Existence and instability of steady states for a triangular cross-diffusion system: a computer-assisted proof

open access: yes, 2017
In this paper, we present and apply a computer-assisted method to study steady states of a triangular cross-diffusion system. Our approach consist in an a posteriori validation procedure, that is based on using a fxed point argument around a numerically ...

A semi-analytical model for deflection analysis of laminated plates with the Newton-Kantorovich-Quadrature method

open access: yesMaterials Research, 2013
A semi-analytical approach for analysis of laminated plates with general boundary conditions under a general distribution of loads is developed. The non-linear equations are solved by the Newton-Kantorovich-Quadrature (NKQ) method which is a combination ...

Rigorous Enclosures of Solutions of Neumann Boundary Value Problems

open access: yes, 2020
This paper is dedicated to the problem of isolating and validating zeros of non-linear two point boundary value problems. We present a method for such purpose based on the Newton-Kantorovich Theorem to rigorously enclose isolated zeros of two point ...

A modified Newton-secant method for solving nonsmooth generalized equations

open access: yesMathematical Modelling and Analysis
In this paper, we study the solvability of nonsmooth generalized equations in Banach spaces using a modified Newton-secant method, by assuming a Hölder condition.

An improvement of the product integration method for a weakly singular Hammerstein equation

open access: yes, 2016
We present a new method to solve nonlinear Hammerstein equations with weakly singular kernels. The process to approximate the solution, followed usually, consists in adapting the discretization scheme from the linear case in order to obtain a nonlinear ...
