Discrete Takagi-Sugeno's Fuzzy Models: Reduction of the Number of LMI in fuzzy control techniques

François Delmotte, Thierry-Marie Guerra, Alexandre Kruszewski

Conditions about the stabilization of Takagi-Sugeno fuzzy models can systematically be derived and solved usually using linear matrix inequality problems. Current research tries to lower any pessimism. However, often it leads to an important increase in the number of decision variables, and…

A new dimensionless number highlighted from mechanical energy exchange during running

Nicolas Delattre, Pierre Moretto

This study aimed to highlight a new dimensionless number from mechanical energy transfer occurring at the centre of gravity (Cg) during running. We built two different-sized spring-mass models (SMM #1 and SMM #2). SMM #1 was built from the previously published data, and SMM #2 was built to be…

Vehicle spacing control using robust fuzzy control with pole placement in LMI region

P.-F. Toulotte, Sebastien Delprat, Thierry-Marie Guerra, Jacques Boonaert

This work presents a robust pole placement in a LMI region for Takagi-Sugeno (TS) (Takagi and Sugeno 1985) fuzzy models. The objective is to find a set of Linear Matrix Inequalities in order to ensure that the linear model poles of the nonlinear TS model remain in a specified region of the complex…

Experimental investigation of a confined flow downstream of a circular cylinder centred between two parallel walls

F. Rehimi, Fethi Aloui, S. Ben Nasrallah, L. Doubliez, J. Legrand

In this work, we present an experimental study of the wall confinement effect on the wake formation behind a circular cylinder of diameter dc=10 mm and of length Lc=30dc. The experiments were performed in a water tunnel with the dimensions (length=300dc, height=3dc, span Lc=30dc). The confinement…

Regeneration engineering for weapon system availability assessment

Maxime Monnin, Benoît Iung, Olivier Sénéchal

Many systems that perform critical missions have to function in hostile environments where operational availability can be affected by internal system failures and external factors such as damage. Traditionally, system dependability has focused on internal causes (e.g., failures), while system…

Behaviour based on decision matrices for a coordination between agents in a urban traffic simulation

René Mandiau, Alexis Champion, Jean-Michel Auberlet, Stéphane Espie, Christophe Kolski

This paper describes a multi-agent coordination mechanism applied to intersection simulation situations. In a goal of urban traffic simulation, we must consider the dynamic interactions between autonomous vehicles. The field of multi-agent systems provides us some studies for such systems, in…

Non-quadratic stabilization conditions for a class of uncertain non linear discrete-time T-S fuzzy models: a new approach

Alexandre Kruszewski, R. Wang, Thierry-Marie Guerra

The discrete-time uncertain nonlinear models are considered in a Takagi-Sugeno form and their stabilization is studied through a non- quadratic Lyapunov function. The classical conditions consider a one- sample variation, here, the main results are obtained considering k samples variation, i.e.,…

Scatter Search for the 0–1 Multidimensional Knapsack Problem

Saïd Hanafi, Christophe Wilbaut

The evolutionary metaheuristic called scatter search has been applied successfully to optimization problems for several years. In this paper, we apply the scatter search technique to the well-known 0-1 multidimensional knapsack problem. We propose a new relaxation-based diversification generator,…
