Vehicle spacing control using robust fuzzy control with pole placement in LMI region

P.-F. Toulotte, Sebastien Delprat, Thierry-Marie Guerra, Jacques Boonaert

This work presents a robust pole placement in a LMI region for Takagi-Sugeno (TS) (Takagi and Sugeno 1985) fuzzy models. The objective is to find a set of Linear Matrix Inequalities in order to ensure that the linear model poles of the nonlinear TS model remain in a specified region of the complex…

Regeneration engineering for weapon system availability assessment

Maxime Monnin, Benoît Iung, Olivier Sénéchal

Many systems that perform critical missions have to function in hostile environments where operational availability can be affected by internal system failures and external factors such as damage. Traditionally, system dependability has focused on internal causes (e.g., failures), while system…

Development and test of a new plantar pressure control device for foot unloading, Élaboration et validation d’un nouveau dispositif de surveillance des pressions plantaires : application à la décharge du pied

Virginie Femery, Francois J Potdevin, A. Thevenon, Pierre Moretto

Objective. – To validate a new plantar pressure control device able to detect excessive plantar pressure on-line and to improve the subject’s awareness of the gait pattern in order to correct and optimize the load distribution patterns. The aim of this study was to verify the feasibility of a…, Valider un nouvel appareil de surveillance des pressions plantaires capable de détecter, en temps réel, des hyperpressions et permettre à l'utilisateur un autocontrôle des évènements dynamiques à l'interface pied-chaussure-sol. Le but de cette étude est de vérifier la faisabilité d'…

Behaviour based on decision matrices for a coordination between agents in a urban traffic simulation

René Mandiau, Alexis Champion, Jean-Michel Auberlet, Stéphane Espie, Christophe Kolski

This paper describes a multi-agent coordination mechanism applied to intersection simulation situations. In a goal of urban traffic simulation, we must consider the dynamic interactions between autonomous vehicles. The field of multi-agent systems provides us some studies for such systems, in…

Non-quadratic stabilization conditions for a class of uncertain non linear discrete-time T-S fuzzy models: a new approach

Alexandre Kruszewski, R. Wang, Thierry-Marie Guerra

The discrete-time uncertain nonlinear models are considered in a Takagi-Sugeno form and their stabilization is studied through a non- quadratic Lyapunov function. The classical conditions consider a one- sample variation, here, the main results are obtained considering k samples variation, i.e.,…

Scatter Search for the 0–1 Multidimensional Knapsack Problem

Saïd Hanafi, Christophe Wilbaut

The evolutionary metaheuristic called scatter search has been applied successfully to optimization problems for several years. In this paper, we apply the scatter search technique to the well-known 0-1 multidimensional knapsack problem. We propose a new relaxation-based diversification generator,…

New convergent heuristics for 0–1 mixed integer programming

Christophe Wilbaut, Said Hanafi

Several hybrid methods have recently been proposed for solving 0-1 mixed integer programming problems. Some of these methods are based on the complete exploration of small neighborhoods. In this paper, we present several convergent algorithms that solve a series of small sub-problems generated by…

The Safe-SADT method for aiding designers to choose and improve dependable architectures for complex automated systems

Vincent Benard, Laurent Cauffriez, Dominique Renaux

Dependability evaluation is crucial to controlling the risks associated with system failure, and for this reason, it is one of the fundamental steps in automated system design. However, the dependability evaluation methods that are currently exploited are not appropriate, given the level of…

A 3D analysis of fore and hindlimb motion during locomotion: comparison of overground and ladder walking in rats

Cyril Garnier, Maurice Falempin, Marie-Hélène Canu

The locomotor pattern, generated by the central pattern generator, is under the dependence of descending and peripheral pathways. The afferent feedback from peripheral receptors allows the animal to correct for disturbances that occur during walking, while supraspinal structures are important for…

Evaluation of agent-based interactive systems : proposal of an electronic informer using Petri Nets

Chi Dung Tran, Houcine Ezzedine, Christophe Kolski

The evaluation of interactive systems has been an active subject of research for many years. Many methods and tools have been proposed but most of them do not take architectural specificities of agent-based interactive systems into account. In addition, electronic informers are popular evaluation…
