Iterative Nonlinear Control of a Semibatch Reactor. Stability Analysis [PDF]

open access: yes, 2005
This paper presents the application of Iterative Nonlinear Model Predictive Control, INMPC, to a semibatch chemical reactor. The proposed control approach is derived from a model-based predictive control formulation which takes advantage of the ...

On Ulam's Type Stability of the Cauchy Additive Equation

open access: yesThe Scientific World Journal, 2014
We prove a general result on Ulam's type stability of the functional equation fx+y=fx+fy, in the class of functions mapping a commutative group into a commutative group. As a consequence, we deduce from it some hyperstability outcomes.

Remark on hyperstability of the general linear equation [PDF]

open access: yesAequationes mathematicae, 2013
We present a result concerning the hyperstability of the general linear equation. Namely, we show that a function satisfying the equation approximately must be actually a solution to it.

Approximate solution of generalized inhomogeneous radical quadratic functional equations in 2-Banach spaces

open access: yesJournal of Inequalities and Applications, 2019
In this paper, using Brzdȩk and Ciepliński’s fixed point theorems in a 2-Banach space, we investigate approximate solution for the generalized inhomogeneous radical quadratic functional equation of the form f(ax2+by2)=af(x)+bf(y)+D(x,y), $$f \bigl(\sqrt{

Stability of the Apollonius Type Additive Functional Equation in Modular Spaces and Fuzzy Banach Spaces

open access: yesMathematics, 2019
In this work, we investigate the generalized Hyers-Ulam stability of the Apollonius type additive functional equation in modular spaces with or without Δ 2 -conditions.

On Stability and Hyperstability of an Equation Characterizing Multi-Cauchy–Jensen Mappings

open access: yes, 2018
Recently, functions of several variables satisfying, with respect to each variable, some functional equation (among them Cauchy’s, Jensen’s, quadratic and other ones) have been studied.

Passive dynamic controllers for nonlinear mechanical systems [PDF]

open access: yes
A methodology for model-independant controller design for controlling large angular motion of multi-body dynamic systems is outlined. The controlled system may consist of rigid and flexible components that undergo large rigid body motion and small ...
