Motion planning for cooperative unicycle-type mobile robots with limited sensing ranges: A distributed receding horizon approach

Michael Defoort, Thierry Floquet, Annemarie Kökösy, Wilfrid Perruquetti

This paper presents a decentralized motion planner for a formation of autonomous mobile robots evolving in an unknown environment with obstacles. The motion planning scheme consists of decentralized receding horizon planners that reside on each vehicle to achieve coordination among formation agents...

Roughness characteristic length scales of belt finished surface

Maxence Bigerelle, A. Gautier, B. Hagege, Jérôme Favergeon, B. Bounichane

Surface integrity, dynamic properties and mechanical characteristics of belt finished surfaces strongly depend on the achieved surface roughness produced by the abrasion process. A new approach based on the scaling analysis of the roughness characterization is introduced on a surface obtained by a...

A membership-function-dependent approach for stability analysis and controller synthesis of Takagi-Sugeno models

Miguel Bernal, Thierry-Marie Guerra, Alexandre Kruszewski

This paper presents a new approach for stability analysis and controller design of Takagi–Sugeno (TS) models. The analysis considers information derived from existing or induced order relations among the membership functions. Partitioning of the state-space and the use of piecewise Lyapunov...

A Triangulation Approach to Asymptotically Exact Conditions for Fuzzy Summations

Alexandre Kruszewski, Antonio Sala, Thierry-Marie Guerra, Carlos Ariño

Many Takagi–Sugeno (T--S) fuzzy control-synthesis problems in the literature are expressed as the problem of finding decision variables in a double convex sum (fuzzy summation) of positive definite matrices. Matrices’ coefficients in the summation take values in the standard simplex. This paper...

Measurements of brake disc surface temperature and emissivity by two-color pyrometry

Thevenet Jean, Siroux Monica, Bernard Desmet

A fiber optic two-color pyrometer was developed for brake disc surface temperature and emissivity measurements. The two-color pyrometer consists of a fluoride glass optical fiber, two HgCdTe detectors equipped with bandwidth filters and a data conditioning and acquisition device. The two-color...

Fuel-Cell Hybrid Powertrain: Toward Minimization of Hydrogen Consumption

J. Bernard, Sebastien Delprat, F.N. Buchi, Thierry-Marie Guerra

In this paper, the powertrain sizing of a fuel-cell hybrid vehicle (FCHV) is investigated. The goal is to determine the fuel-cell system (FCS) size, together with the energy storage system (ESS) size, which leads to the lowest hydrogen consumption. The power source (FCS + ESS) capabilities should...

Trade-Off Exploration for Target Tracking Application in a CustomizedMultiprocessor Architecture

Jehangir Khan, Smail Niar, Mazen Saghir, Yassin El Hillali, Atika Rivenq

This paper presents the design of an FPGA-based multiprocessor-system-on-chip (MPSoC) architecture optimized for Multiple Target Tracking (MTT) in automotive applications. An MTT system uses an automotive radar to track the speed and relative position of all the vehicles (targets) within its field...

Porous silicon based microdevice for reversed phase liquid chromatography

E. Méry, S. Alekseev, Florence Portet-Koltalo, C. Morin, Damien Barbier, V. Zaitsev, P. Desbène

This paper deals with On-Chip-Chromatography separation systems micromachined on porous silicon. Reversed phase C18 was prepared on the porous silicon base and characterised by means of FTIR and water contact angle measurements. From this preliminary study, a liquid chromatography microdevice...

A 3D analysis of fore- and hindlimb motion during overground and ladder walking: comparison of control and unloaded rats

Marie-Hélène Canu, Cyril Garnier

During locomotion, muscles are controlled by a network of neurones located in the spinal cord and by supraspinal structures. Alterations in that neuromuscular system have a functional impact, in particular on locomotion. The hindlimb unloading (HU) model in rat has been commonly used to generate...

Un modèle générique unifié de représentation et de résolution de problèmes pour la réutilisation des connaissances. Application à l'analyse de sécurité des systèmes de transport automatisés, Unified and Generic Model of problems representation and resolution for knowledge reusing. Application to security analysis of automated transport systems

Lassaad Mejri, Habib Hadj-Mabrouk, Patrice Caulier

La résolution de problèmes dynamiques confronte l'opérateur humain à de nombreuses tâches à forte composante de prise d'information et de décision, sous contrainte temporelle. Si elle requiert des savoirs et des savoir-faire fondamentaux, la résolution de problèmes dynamiques nécessite..., Dynamic problem resolution confronts human operator to many tasks which require a treatment of a great lot of information, a decision making, under temporal constraints. If it requires knowledge and a fundamental know-how, dynamic problem solving necessitates also expertise exploitation, both...
