Fuzzy steering control for autonomous vehicles under actuator saturation: Design and experiments

Tran Anh-Tu Nguyen, Chouki Sentouh, Jean-Christophe Popieul

Abstract This paper presents a new control method for autonomous vehicles. The design goal is to perform the automatic lane keeping under multiple system constraints, namely actuator saturation of the steering system, roads with unknown curvature and uncertain lateral wind force. Such system…

Meshless modeling of bending behavior of bi-directional functionally graded beam structures

Jiao Li, Yanjin Guan, Guoqun Zhao, Jun Lin, Hakim Naceur, Daniel Coutellier

Bi-directional Functionally Graded Materials (FGMs) is of more and more focus in special engineering application like aerospace craft at high altitude and speed. In this paper, bending analysis of this type Functionally Graded Beam (FGB) is performed by a proposed meshless Total Lagrangian (TL)…

Deep learning features for robust facial kinship verification

Amina Tidjani, Abdelmalik Taleb-Ahmed, Djamel Samai, Aiadi Kamal Eddine

Facial automatic kinship verification is a novel challenging research problem in computer vision. It performs the automatic examining of the facial attributes and expecting whether two persons have a biological kin relation or not. In this study, the authors introduce a novel learning method for…

Low additional thickness under the toes could change upright balance of healthy subjects

Frédéric Viseux, Franck Barbier, Philippe Villeneuve, Antoine Lemaire, Pascal Charpentier, Sebastien Leteneur

The purpose of the study was to evaluate the effect of an additional thickness placed under the toes (TUT) on the CoP measures and to determine the optimum thickness required to maximize the postural control performance. Four conditions were compared: TUT 0 (control), 0.8, 3, and 6 mm and four…

Strain rate effects on the compressive response of wood and energy absorption capabilities – Part B: Experimental investigation under rigid lateral confinement

Jérémy Wouts, Grégory Haugou, M. Oudjene, Hervé Morvan, Daniel Coutellier

The compressive properties of spruce and beech wood species at a large range of strain rates – from 0.001 to 600 – under rigid lateral confinement have been investigated, using an original experimental device especially developed for the purpose. The work is motivated by the need to explore the…

Implementation of standard penalty procedures for the solution of incompressible Navier–Stokes equations, employing the element-free Galerkin method

Juan Carlos Álvarez-Hostos, Victor D. Fachinotti, Alirio J. Sarache Piña, Alfonso D. Bencomo, Eli Saúl Puchi-Cabrera

The present work introduces an alternative implementation of the element-free Galerkin method (EFGM) for the steady incompressible Navier–Stokes equations. The linear momentum balance and mass conservation equations have been developed on the basis of this global weak formulation. The weak forms of…

Hydrodynamic oscillations inside deep cavities with wall offset

Denis Cornu, Marc Lippert, Franck Kerhervé, Fethi Aloui, Laurent Keirsbulck

The paper focuses on the pressure amplitude response of deep cavities at low Mach numbers with wall offset between the leading and trailing edges. Three wall offsets of , and are considered for different Reynolds numbers and values of length-to-depth ratio (=0.24, 0.48 and 0.65). Present…

On the consensus tracking investigation for multi-agent systems on time scale via matrix-valued Lyapunov functions

Serhii Babenko, Michael Defoort, Mohamed Djemai, Serge Nicaise

This paper is devoted to the leader–follower consensus problem for high-order multi-agent systems with inherent nonlinear dynamics evolving on an arbitrary time domain. This problem is investigated using the time scale theory. Based on this theory, some sufficient conditions are derived to…

Distributed leader-follower consensus for a class of semilinear second order multi-agent systems using time scale theory

Serhii Babenko, Michael Defoort, Mohamed Djemai, Serge Nicaise

The problem of distributed leader‐follower consensus for second‐order linear multiagent systems with unknown nonlinear inherent dynamics is investigated in this paper. It is assumed that the dynamic of each agent is described by a semilinear second‐order dynamic equation on an arbitrary time scale…

Assessing Cyber-Physical Systems to Balance Maintenance Replacement Policies and Optimize Long-Run Average Costs for Aircraft Assets

Marco Andreacchio, Abdelghani Bekrar, Rachid Benmansour, Damien Trentesaux

Many aircraft assets are subject to both preventive (scheduled) and corrective (unscheduled) replacement policies to ensure adequate levels of reliability and availability. The problem, particularly for assets that exist in large quantities, is that preventive replacement tasks often involve…
