Boundary control and observer design for an uncertain wave process by second-order sliding-mode technique [PDF]

open access: yes, 2013
The primary concern of the present paper is the regulation of an uncertain wave process with collocated boundary sensing and Neumann-type actuation. It exhibits an unknown constant elasticity parameter and it is affected by a boundary disturbance, which ...

Exponential stabilization of an Euler-Bernoulli beam under boundary control

open access: yesJournal of Innovative Applied Mathematics and Computational Sciences, 2023
We study the free vibration of an Euler-Bernoulli beam without internal damping. By applying suitable control at the free boundary, we can exponentially dampen these vibrations.

Trial methods for Bernoulli's free boundary problem [PDF]

open access: yes, 2014
Free boundary problems deal with solving partial differential equations in a domain, a part of whose boundary is unknown – the so-called free boundary. Beside the standard boundary conditions that are needed in order to solve the partial differential ...

A PDE Model Approach to Formation Control of Large-Scale Mobile Sensor Networks with Boundary Uncertainties

open access: yesAxioms, 2022
This paper investigates the formation problem of an array of large-scale mobile sensor networks. A new framework for the dynamic of mobile sensors as a continuum described by the parabolic system with boundary disturbance is proposed.

Influence of boundary layer transition on the trajectory optimisation of a reusable launch vehicle [PDF]

open access: yes, 2014
Based on flight experience from the Space Shuttle programme, it is well known that mis-prediction of the effects of boundary layer transition represents one of the highest technical risks when designing a Reusable Launch Vehicle.

Stabilization of a nonlinear Euler-Bernoulli viscoelastic beam subjected to a neutral delay [PDF]

open access: yesTheoretical and Applied Mechanics
An approach is implemented in this article to analyze the decay rate of nonlinear beams according to the Euler–Bernoulli equation in the context of rheological viscoelastic damping deformations taking into account the neutral type delay.

An Approximation of Solutions for the Problem with Quasistatic Contact in the Case of Dry Friction

open access: yesMathematics, 2021
In this paper, we discuss the question of finding an optimal control for the solutions of the problem with dry friction quasistatic contact, in the case that the friction law is modeled by a nonlocal version of Coulomb’s law.
