New stabilization conditions for continuous fuzzy models using their discretized forms

Ameni Ellouze, Mohamed Ksantini, Jimmy Lauber, François Delmotte, Mohamed Chtourou

Purpose – The purpose of this paper is to deal with the stabilization of the continuous-time Takagi-Sugeno (TS) fuzzy models by using their discretized models. Design/methodology/approach – In this case, a discrete model is obtained from the discretization of the continuous TS fuzzy model. The…

Multiscale assessment of the accuracy of surface replication

Julie Marteau, M Wieczorowski, Y Xia, Maxence Bigerelle

This paper presents a methodology for the assessment of replication accuracy using a multiscale approach. It focuses on the quantification of 'metrological replication accuracy', which is a direct comparison of the topography of a surface and its replica. This methodology uses an analysis…

Evaluation of Damage and Fracture Mechanisms of Different Characteristic Honeycomb Structures Under Thermomechanical Loading

A. Settet, Abdelkader Nour, Hamou Zahloul, Hakim Naceur

A model able to predict the delamination mechanisms of composite honeycomb structures under thermal loading is presented. The use of a simulation software for some applications may not be sufficient to obtain the results expected; hence, the interest in developing modular calculation codes which…

An improved robust stabilization method for discrete-time fuzzy systems with time-varying delays

Antonio Gonzalez Sorribes, Thierry-Marie Guerra

This note focuses on the robust stabilization of discrete-time fuzzy uncertain systems with time-varying delays under a delayed nonparallel distributed compensation scheme. The key idea is twofold: first, the linear matrix inequalities (LMI) proposed here are shown to generalize some previous…

Lyapunov‐based robust control design for a class of switching non‐linear systems subject to input saturation: application to engine control

Anhtu Nguyen, Michel Dambrine, Jimmy Lauber

Control technique based on the well-known Takagi–Sugeno (T–S) models offers a powerful and systematic tool to cope with complex non-linear systems. This study presents a new method to design robust H∞ controllers stabilising the switching uncertain and disturbed T–S systems subject to control input…

Experimental investigation on heat pipe cooling for Hybrid Electric Vehicle and Electric Vehicle lithium-ion battery

Thanh-Ha Tran, Souad Harmand, Bernard Sahut

In this work, we explored the use of heat pipe as cooling device for a specific HEV lithium-ion battery module. The evaporator blocks of heat pipe modules were fixed to a copper plate which played the role of the battery cooling wall. A flat heater was glued to the other surface of the copper plate…

Optimal control based algorithms for energy management of automotive power systems with battery/supercapacitor storage devices

Tran Anh-Tu Nguyen, Jimmy Lauber, Michel Dambrine

The objective of this work is to show how to control the electric power systems of a vehicle in such a manner that their power flows should be optimized in the sense of energy efficiency. As will be seen, the control problem considered in this work can be formulated as an optimization problem in…

Reverse flow region associated to a heat transfer in a turbulent wall jet

Nora Nait Bouda, A. Babbou, Souad Harmand

A numerical study is performed in order to investigate the effects of the inlet flow structure on the flow and heat transfer characteristics in the reattachment zone downstream a backward facing step. Indeed, two inlet flow configurations are considered; a turbulent wall jet (WJ) which presents a…

Interpolation functions of a hybrid-Trefftz perforated super-element featuring nodes on the hole boundary

Claire Hennuyer, Nicolas Leconte, Bertrand Langrand, Eric Markiewicz

The topic of the paper is related to the macroscopic modelling of riveted assemblies for full-scale aircraft structures subjected to crash/impact loadings. “Super-elements” have been developed to model the rivet and its rupture. However, stress concentrations in riveted assemblies can also initiate…
