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…

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…

On Nonlinear Control for Lane Keeping Assist System in Steer-By-Wire Road Wheeled Vehicles

Gabriele Perozzi, Chouki Sentouh, Jérôme Floris, Jean-Christophe Popieul

This paper deals with the design of a lane keeping system in steer-by-wire road four-wheeled vehicles using a nonlinear controller. The controller is designed to take into account the driver's behavior and availability and to control the wheels' angle of the steer system. A high order…

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…

Adaptive Fuzzy Control for Multivariable Nonlinear Systems with Indefinite Control Gain Matrix and Unknown Control Direction

Salim Labiod, Thierry-Marie Guerra

In this paper, we focus on the direct adaptive fuzzy control design for a class of uncertain MIMO nonlinear systems with indefinite control gain matrix and unknown control direction. The control design is based on the approximation of an unknown ideal control law that can meet the control objective…

Ethical stakes of Industry 4.0

Damien Trentesaux, Emmanuel Caillaud

Industry 4.0 provokes a shift in the way production systems are designed and used that raises ethical questions. This shift stems from several features relevant to Industry 4.0, specifically the increase of the importance of the digital world and the fostering of the development of more autonomous…

LPV Framework for Non-Linear Dynamic Control of Soft Robots using Finite Element Model

Maxime Thieffry, Alexandre Kruszewski, Thierry-Marie Guerra, Christian Duriez

This work presents a methodology to control soft robots using a reduced order nonlinear finite element model. The Linear Parameter-Varying (LPV) framework is used both to model the robot along a prescribed trajectory and to design its control law. Model reduction algorithms along with radial basis…

Designing Optimal Scaffold Topographies to Promote Nucleus-Guided Mechanosensitive Cell Migration Using in Silico Models, Concevoir, à l'aide modèles cellulaires in silico, des topographies optimales de biomatériaux pour promouvoir la migration cellulaire mécano-sensible guidée par le noyau

Maxime Vassaux, Laurent Pieuchot, Karine Anselme, Maxence Bigerelle, Jean-Louis Milan

Computational models have become an essential part of exploratory protocols in cell biology, as a complement to in vivo or in vitro experiments. These virtual models have the twofold advantage of enabling access to new types of data and validate complex theories. The design of mechanically…

Predicting manual wheelchair initiation movement with EMG activity during over ground propulsion

Soufien Chikh, Samuel Boudet, Antonio Pinti, Cyril Garnier, Rawad El Hage, Fairouz Azaiez, Eric Watelain

Context/Objective: This is a preliminary study of movement finalities prediction in manual wheelchairs (MWCs) from electromyography (EMG) data. MWC users suffer from musculoskeletal disorders and need assistance while moving. The purpose of this work is to predict the direction and speed of…
