Design and Construction of a Multifunction Piezoelectric Transformer

Adil Eddiai, Mounir Meddad, Mohamed Rguiti, Aïda Chérif, Christian Courtois

In recent years, piezoelectric materials have particularly found advantageous field of application in electrical energy’s conversion. Especially, the piezoelectric transformers are becoming more and more usable in electrical devices owing to several advantages such as small size, high efficiency,…

Reducing the number of vertices in some Takagi-Sugeno models: example in the mechanical field

Thierry-Marie Guerra, Miguel Bernal, Mathias Blandeau

This paper is concerned with the building of application-oriented model-based Takagi-Sugeno models that arise from sector nonlinearity methodology. Despite its exactness, this modeling technique produces a polytopic embedding with a number of vertices of 2 raised to the number of nonlinearities…

Sublinearity of the number of semi-infinite branches for geometric random trees

David Coupier

The present paper addresses the following question: for a geometric random tree in R-2, how many semi-infinite branches cross the circle C-r centered at the origin and with a large radius r? We develop a method ensuring that the expectation of the number X-r of these semi-infinite branches is o (r…

Usage des points massiques et des courbes de Bézier pour la modélisation des cubiques

Karine Serier, Jean-Paul Becar, Lionel Garnier

Cet article étend l'étude des points singuliers et des points d'inflexion des courbes rationnelles cubiques en s'ins-pirant de la méthode proposée par M. Sakai dans le cadre des points massiques. L'intérêt des points massiques permet de représenter une boucle c'est à dire…

Simultaneous Estimation of Vehicle Lateral Dynamics and Driver Torque using LPV Unknown Input Observer

Tran Anh-Tu Nguyen, Thierry-Marie Guerra, Chouki Sentouh

This paper presents a new method to estimate simultaneously both the vehicle state and the driver torque. To take into account the time-varying nature of the longitudinal speed, the vehicle system is transformed into a polytopic LPV model with a reasonable level of numerical complexity. The design…
