Coupling a genetic algorithm with the distributed arrival-time control for the JIT dynamic scheduling of flexible job-shops

Gabriel Zambrano Rey, Abdelghani Bekrar, Vittaldas V. Prabhu, Damien Trentesaux

In order to increase customer satisfaction and competitiveness, manufacturing systems need to combine flexibility with Just-in-Time (JIT) production. Until now, research on JIT scheduling problems has been mostly limited to high volume assembly lines rather than job-shop-like systems, due to their...

Self-triggered control for multi-agent systems under a directed switching graph

Michael Defoort, Stefano Di Gennaro, Mohamed Djemai

This paper presents the design of a self-triggered methodology for control of multi-agent systems. Conditions that guarantee the existence of a self-triggered strategy solving the consensus problem, are provided for first order systems under fixed and switching topologies. A methodology for the...

Active diagnosis for a class of switched systems

Jérémy van Gorp, Alessandro Giua, Michael Defoort, Mohamed Djemai

This paper deals with active diagnosis for a class of switched systems which may not satisfy the classical diagnosability conditions. A Mealy Machine modeling is used to define an appropriate diagnoser which reduces the uncertain state subset. An algorithm combining the proposed diagnoser and a...

Diagnostic et observation d'une classe de systèmes dynamiques hybrides. Application au convertisseur multicellulaire série, Diagnosis and observation of a class of hybrid dynamical systems Application to the multicellular converter

Jérémy van Gorp

Cette thèse s’intéresse au diagnostic et à l’observation de systèmes linéaires à commutations et à l’application au convertisseur multicellulaire série. L’objectif est de proposer des solutions pour des sous-systèmes non-observables au sens classique et dont des fautes continues ou discrètes..., This thesis deals with the diagnosis and the observation of a large class of switched linear systems with an application to the multicellular converter. The objective is to provide solutions for non-observable subsystems in the classical sense which can be influenced by continuous or discrete...

Fault Detection and Isolation of Aircraft Air Data/Inertial system

Denis Berdjag, Jérome Cieslak, Ali Zolghadri

A method for failure detection and isolation (FDI) for redundant aircraft sensors is presented. The outputs of the concerned sensors are involved in the computation of §ight control laws, and the objective is to eliminate any fault before propagation in the control loop when selecting a unique §...

Contrôle de la contraction musculaire volontaire après un traumatisme médullaire cervical : Etude de la réorganisation des activations musculaires et corticales, Control of actual muscular contraction after cervical spinal cord injury: Study of the reorganization of cortical and muscular activations

Sylvain Cremoux

La réalisation d'une action motrice implique l'activation simultanée des muscles agonistes et antagonistes contrôlés par le système nerveux central. Suite à un traumatisme médullaire, la détérioration de la moelle épinière entraine à la fois une perte d'efficience motrice et des..., The realization of a motor action involves simultaneous activation of both agonist and antagonist muscles controlled by the central nervous system. Following spinal cord injury, damage to the spinal cord causes both a loss of motor efficiency and changes in the control of muscle activations. In the...

Reduced numerical model to investigate the dynamic behaviour of honeycombs under mixed shear–compression loading

Rami Tounsi, Bassem Zouari, Fahmi Chaari, Eric Markiewicz, Grégory Haugou, Fakhreddine Dammak

Cellular materials such as aluminium honeycombs combine lightweight with an efficient crash energy absorption capability. They have a major role in a wide range of transport applications to reduce gas emission by the design of lighter structures but remaining safe in accident case. Many...

Analysis of thin composite structures using an efficient hex-shell finite element

Seddik Shiri, Hakim Naceur

In this paper a general methodology for the modeling of material composite multilayered shell structures is proposed using a Hex-shell finite element modeling. The first part of the paper is devoted to the general FE formulation of the present composite 8-node Hex-shell element called SCH8, based...

Development of a new nonlinear numerical material model for woven composite materials accounting for permanent deformation and damage

Olivier Cousigné, David Moncayo, Daniel Coutellier, Pedro Camanho, Hakim Naceur, Steffen Hampel

Due to their draping, stiffness, improved ductility and damage tolerance properties woven composites are being increasingly used for the construction of crash-relevant structural parts. Textile composites may depict a nonlinear behavior along several directions. Moreover, considerably-thick...
