Tabu search: global intensification using dynamic programming

Christophe Wilbaut, Saïd Hanafi, Arnaud Fréville, Stefan Balev

Tabu search has proven highly successful in solving hard combinatorial optimization problems. In this paper, we propose a hybrid method that combines adaptive memory, sparse dynamic programming, and reduction techniques to reduce and explore the search space. Our approach starts with a bi-partition...

A support method for the contextual interpretation of biomechanical data.

Emmanuel Roux, Anne-Pascale Godillon-Maquinghen, Patrice Caulier, Stéphane Bouilland, Denis Bouttens

In the clinical field, biomechanical data provided by advanced technical devices are still underexploited. Data analysis usually consists of extracting attributes or computing synthetic values from temporal data and exploiting them by means of a monovariable statistical method. This article...

A new formalism for designing and specifying RAMS parameters for complex distributed control systems: the Safe-SADT formalism

Laurent Cauffriez, Vincent Benard, Dominique Renaux

Dependability evaluation is a fundamental step in distributed control system design. However, the current dependability evaluation methods are not appropriate due to the level of complexity of such systems. Given the ineffectiveness of these methods, we propose the Safe-SADT formalism for...

Modelling of an interactive system with an agent-based architecture using Petri nets, application of the method to the supervision of a transport system

Houcine Ezzedine, Abdelwaheb Trabelsi, Christophe Kolski

This article presents an original method using high level Petri nets for the specification and design of interactive systems. We suggest an agent oriented architecture based on the classic components of an interactive application (application, dialogue control, interface with the application). Our...

Modélisation et commande d'un véhicule à deux roues

Hélène Tirmant, Laurent Vermeiren, Thierry-Marie Guerra, Alexandre Kruszewski, Michel Null Parent

Cet article présente des résultats sur la modélisation et la commande d'un prototype de véhicule à 2 roues nommé le B2, basé sur le principe du pendule inversé., This paper presents the results on the modeling and the control of a two-wheeled prototype, the vehicle named B2, based on the inverted pendulum principle. Its goal is to reduce the problems due to the vehicles in the center of the towns. A Takagi-Sugeno fuzzy model has been developed from the...

Simulation and assessment of power control strategies for a parallel hybrid car

Gino Paganelli, Thierry-Marie Guerra, Sebastien Delprat, Jean-Jacques Santin, M Delhom, E. Combes

The aim of this paper is to propose a power control strategy for hybrid electrical vehicles. This strategy uses a fuel consumption criterion with battery charge sustaining. It is based on an instantaneous minimization of the equivalent fuel flow. Two comparisons are performed to evaluate the...

Perspectives of fuzzy systems and control

Antonio Sala, Thierry-Marie Guerra, Robert Babuška

Although fuzzy control was initially introduced as a model-free control design method based on the knowledge of a human operator, current research is almost exclusively devoted to model-based fuzzy control methods that can guarantee stability and robustness of the closed-loop system. State-of-the-...

Bootstrap analysis of the relation between initial adhesive events and long-term cellular functions of human osteoblasts cultured on biocompatible metallic substrates

Maxence Bigerelle, Karine Anselme

Classically, the evaluation of cellular adhesion of cells on substrates is limited to the evaluation of cell attachment after some hours. We have claimed for several years that this evaluation is incomplete concerning the evaluation of cell adhesion and more precisely of the quality of the in vitro...

Moving least squares response surface approximation: Formulation and metal forming applications

Piotr Breitkopf, Hakim Naceur, Alain Rassineux, Pierre Villon

We focus on a successive response surface method for the optimization problems. The response surfaces are built using Moving Least Squares approximations constructed within a moving region of interest. Our first approach is an extension of pattern search algorithms with a fixed pattern panned and...

Adaptive fuzzy control of a class of MIMO nonlinear systems

Salim Labiod, Mohamed Seghir Boucherit, Thierry-Marie Guerra

This paper presents two indirect adaptive fuzzy control schemes for a class of uncertain continuous-time multi-input multi-output nonlinear dynamic systems. Within these schemes, fuzzy systems are employed to approximate the plant's unknown nonlinear functions and robustifying control terms...
