Stability Analysis of Switched Linear Systems on Non-Uniform Time Domain with Unstable Subsystems

Fatima Zohra Taousser, Michael Defoort, Mohamed Djemai, Serge Nicaise

This paper deals with the stability analysis of a class of switched linear systems evolving on an arbitrary time domain. This class consists of a set of unstable linear continuous-time and unstable linear discrete-time subsystems. Using the time scale theory, some sufficient conditions are derived…

Unknown input observer based on discrete-time nonlinear descriptor model for understanding sitting control

Mathias Blandeau, Thierry-Marie Guerra, Víctor Estrada Manzo, Philippe Pudlo, François Gabrielli

The present paper studies sitting control for persons with complete thoracic spinal cord injury by means of automatic control. The methodology begins by modeling sitting control, after a discretization of the nonlinear descriptor model is computed, then a Takagi-Sugeno model is obtained for further…

A method for designing levels of automation based on a human-machine cooperation model

Lydia Habib, Marie-Pierre Pacaux-Lemoine, Patrick Millot

Human-machine systems are omnipresent in our everyday life. These systems are very important; they allow human and machine understanding and working together efficiently. But poor choices during its design can have important impacts, principally in terms of safety, security and performance. The…

Literature Review of Building Information Modeling (BIM) Intended for the Purpose of Renovation Projects

Laurent Joblot, Thomas Paviot, Dominique Deneux, Samir Lamouri

This article focuses on the relevance of a digital approach as BIM in the particularly dynamic and diversified renovation sector, mainly driven by micro enterprises (μEnt). The state of the art shows that few scientific references are devoted to this subject and that the technologies and tools…

A robust and fault tolerant approach for automatic train stop control system design

Braulio Norberto Aguiar Cota, Denis Berdjag, Bernard Demaya, Thierry-Marie Guerra

This paper is about an advanced braking control strategy for rail transportation systems. The motivation is to improve the efficiency of the control in real-world conditions taking into account modeling errors, unknown perturbations and occurring failures. This will allow traffic frequency…

State constrained hybrid vehicle optimal energy management: an interior penalty approach

Tariq Kareemulla, Sebastien Delprat, Ludwig Czelecz

In simulation, hybrid vehicle energy management can be formulated as a state constrained optimal control problem. Pontryagin’s Minimum Principle provides necessary optimality conditions. Due to the state constraints, these conditions are non-solvable without any additional information about the…

Some Generalizations of Pachpatte Inequalities on Time Scales

Bacem Ben Nasser, Khaled Boukerrioua, Michael Defoort, Mohamed Djemai, Mohamed Ali Hammami

This paper deals with some generalizations of certain inequalities of Pachpatte-type, on time scales, using elementary analytic methods. To show the feasibility of the obtained inequalities, an illustrative example is also introduced.

A comparison of different upper-bound inequalities for the membership functions derivative

Victor Campos, Tran Anh-Tu Nguyen, Reinaldo Martinez Palhares

When using fuzzy Lyapunov functions for continuous-time Takagi-Sugeno fuzzy systems, it is common to have to deal with the membership functions’ time derivative. Several upper-bound inequalities have been proposed in the literature in order to deal with these derivatives in a Linear Matrix…

A New Scheme for Haptic Shared Lateral Control in Highway Driving Using Trajectory Planning

Mohamed Amir Benloucif, Tran Anh-Tu Nguyen, Chouki Sentouh, Jean-Christophe Popieul

Conflicts between the driver and systems for automated steering are important issues that affect the safety of the driver and the acceptability of the system. This paper presents a new framework for shared lateral control on highway driving using trajectory planning. The core idea of this work is…

Dynamics of the recirculating areas of a forward-facing-step

Anthony Graziani, Franck Kerhervé, Marc Lippert, Laurent Keirsbulck, David Uystepruyst, Robert J. Martinuzzi

The dynamics of the velocity and surface pressure fields in the recirculating regions upstream of the foot of a forward-facing step and downstream of the step corner are investigated experimentally for a thin turbulent oncoming boundary layer at a Reynolds number, based on the step height, of 105.…
