A Discrete-Time Matching Filtering Differentiator

Jose Eduardo Carvajal Rubio, Juan Diego Sanchez-Torres, Michael Defoort, Alexander Loukianov, Mohamed Djemai

This paper presents a time discretization of therobust exact filtering differentiator, a sliding mode differentiatorcoupled to filter, which provides a suitable approximation to thederivatives of some noisy signals. This proposal takes advantageof the homogeneity of the differentiator, allowing the…

Behavior of the square-back Ahmed body global modes at low ground clearance

Baptiste Plumejeau, Laurent Keirsbulck, Sebastien Delprat, Marc Lippert, Wafik Abassi

The present work aims to study the evolution of the wake-flow dynamic, including the shear-layers interactions phenomena and the global modes behavior of a square-back Ahmed body with a width to height aspect ratio, w/h, of 1.346. Various ground-clearance configurations around the critical case…

Strength and failure of an aluminum/PA66 self-piercing riveted assembly at low and moderate loading rates: Experiments and modeling

Nicolas Leconte, Benjamin Bourel, Franck Lauro, Claudiu Badulescu, Eric Markiewicz

The self piercing riveting (SPR) process is increasingly used in the automotive industry due to its ability to connect multi-materials for weight reduction considerations. The strength and failure of such multi-material assemblies need to be characterized and modelled for full-scale structural…

Experimental Investigations of the Surface Groove Effect in Taylor-Couette-Poiseuille Flow

Lamia Gaied, Fethi Aloui, Marc Lippert, Emna Berrich

In this paper, we investigate the effects of an imposed axial flow on hydrodynamic instabilities’ Couette-Taylor flow in the case where the wall of the inner cylinder of the system is grouved. Without imposed axial flow, the basic flow of a fluid between two coaxial cylinders known by Couette flow…

Experimental and Numerical Investigations of Unsteady Flows Downstream Confined Rectangular Obstacles

Fethi Aloui, Amal Elawady

In this work, we present an experimental and numerical study in a horizontal duct with a rectangular cross-section (300 × 30mm2). In the middle of this cross-section, a rectangular obstacle (20 × 10mm2) then a squared obstacle (10 × 10mm2) were placed in order to study experimentally and…

Lattice Boltzmann Method Based on Large-Eddy Simulation (LES) Used to Investigate the Unsteady Turbulent Flow on Series of Cavities

Insaf Mehrez, Ramla Gheith, Fethi Aloui

A numerical study is proposed to analyze the turbulent flow structures. This paper aims to determine the effect of the series of the cavities. The configuration is similar to that represented by two walls with infinite width, one of which is mobile and the other is fixed. The series of cavity are…

Stabilizing unstable biomechanical model to understand sitting stability for persons with spinal cord injury

Thierry-Marie Guerra, Mathias Blandeau, Tran Anh-Tu Nguyen, Hajer Srihi, Antoine Dequidt

This paper deals with the stabilization of a new open-loop unstable non-linear biomechanical model to represent a person living with a spinal cord injury. The computational complexity of the model when using the Takagi-Sugeno formalism is increased compared to previous models which is a source of…

Designing fuzzy descriptor observer with unmeasured premise variables for head-two-arms-trunk system

Tran Anh-Tu Nguyen, Jun-Tao Pan, Thierry-Marie Guerra, Mathias Blandeau, Weiwei Zhang

Using the technique of unknown input observer, this paper aims at estimatinginternal variables of people living with a complete spinal cord injury (SCI). The goal is to providea better understanding on the sitting control strategy of SCI people. The observer design is basedon a Head-Two-Arms-Trunk…
