Joint torques estimation in human standing based on a fuzzy descriptor unknown inputs observer

Kevin Guelton, Sebastien Delprat, Thierry-Marie Guerra

An alternative to inverse dynamics joint torques estimation in standing human is proposed by the use of an unknown input observer that allows the real time estimation of both the joint torques and the angular velocities from angular positions measurement. To design such observer, a state space…

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…

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…

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…

Modelling of cognitive activity during normal and abnormal situations using Object Petri Nets, application to a supervision system

Houcine Ezzedine, Christophe Kolski

This article presents a method for the modelling of cognitive activity using Object Petri Nets. The method includes the recognition of the various classes of situation (normal and abnormal) which human operators are likely to meet whilst performing their tasks. Each of these classes is described…
