A 3D fourth order fabric tensor approach of anisotropy in granular media

Jamila Rahmoun, Djimedo Kondo, Olivier Millet

We propose a micromechanical approach for granular media, with a particular account of the texture-induced anisotropy and of the strain localization rule. The approach is mainly based on the consideration of a fourth order fabric tensor able to capture general anisotropy which can be induced by...

A Hybrid Algorithm for the Unbounded Knapsack Problem

Vincent Poirriez, Nicola Yanev, Rumen Andonov

This paper presents a new approach for exactly solving the Unbounded Knapsack Problem (UKP) and proposes a new bound that was proved to dominate the previous bounds on a special class of UKP instances. Integrating bounds within the framework of sparse dynamic programming led to the creation of an...

A third order sliding mode controller for a stepper motor

Michael Defoort, Frédéric Nollet, Thierry Floquet, Wilfrid Perruquetti

This paper deals with the robust control problem of a stepper motor subject to parameter uncertainties and load torque perturbation. The developed algorithm is based on third-order sliding-mode control such that a desired angular motor position is accurately tracked. The proposed scheme requires...

Evaluation of agent-based interactive systems, application to an information assistance system: first results

Abdelwaheb Trabelsi, Houcine Ezzedine, Christophe Kolski

The evaluation of interactive systems is a wide and rich research domain: many methods, criteria and tools are available. In this article, we are focused on agent-based interactive systems. We first describe the agent oriented architecture used in our researches. Then we propose an evaluation...

Performance-Based Reactive Navigation for Nonholonomic Mobile Robots

Michael Defoort, Jorge Palos, Annemarie Kökösy, Thierry Floquet, Wilfrid Perruquetti

This paper presents an architecture for the navigation of an autonomous mobile robot evolving in environments with obstacles. Instead of addressing motion planning and control in different contexts, these issues are described in connected modules with performance requirement considerations. The...

A novel higher order sliding mode control scheme

Michael Defoort, Thierry Floquet, Annemarie Kökösy, Wilfrid Perruquetti

A higher order sliding mode control algorithm is proposed for a class of uncertain multi-input multi-output nonlinear systems. This problem can be viewed as the finite time stabilization of a higher order input-output dynamic system with bounded uncertainties. The developed control scheme is based...
