Tubes à rayons X Résumé : Pantograph active control is considered as a means to improve the current collection quality in high-speed railways. Different studies have focused on the assessment of pantograph control systems, addressing actuator configurations and control strategies, mainly by means of numerical experiments. In the last few years, it has become possible to transfer the knowledge gained from numerical experiments to real operating conditions. Due to the high cost of on-track tests, which are necessary for the final assessment of active pantograph performances, it is desirable to perform these tests on a system that has already demonstrated its capabilities with less expensive laboratory tests, in which at least the basic features of the real operating conditions are reproduced. This paper deals with the development of a hardware-in-the-loop (HIL) test rig, which allows the reproduction of the dynamical interaction between the overhead lines and the pantograph in high-speed railways. The HIL test rig makes it possible to verify the control strategies, the electrical drive configurations for active control, and the contact force estimation procedures on a real pantograph under conditions that are similar to those encountered on the real line. Some examples of test bench applications for pantograph active control and contact force estimation are also presented.

Plug-n hybrid electric vehicle / Mapelli, Ferdinando Luigi in IEEE transactions on industrial electronics, Vol. 57 N° 2 (Fevrier 2010)  

Public ISBD [article]  inIEEE transactions on industrial electronics > Vol. 57 N° 2 (Fevrier 2010) . - pp. 598 - 607 Titre : Plug-n hybrid electric vehicle : modeling, prototype realization, and inverter losses reduction analysis Type de document : texte imprimé Auteurs : Mapelli, Ferdinando Luigi, Auteur ; Tarsitano, Davide, Auteur ; Mauri, Marco, Auteur Article en page(s) : pp. 598 - 607 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Direct self-control (DSC) Energetic model Inverter efficiency losses Modeling and simulation plug-in hybrid electric vehicle (PHEV) Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : Nowadays, the greatest part of the effort to reduce pollution emissions is directed toward the hybridization of automotive drive trains. In particular, the design of hybrid vehicles requires a complete system analysis, including the optimization of the electric and electronic devices installed on the vehicle and the design of all the mechanical connections between the different power sources to reach the required performances. The aim of this paper is to describe the design and prototype realization of a plug-in hybrid electrical vehicle (PHEV). Specifically, an energetic model was developed in order to analyze and optimize the power flux between the different parts. This model was experimentally validated using a prototype PHEV. In addition, in order to improve the driving range in an all-electric model (all-electric range), a detailed analysis of the inverter control was performed, because this component is one of the key components of the power train. In order to reduce inverter losses and dimensions, several control methods can be adopted. In this paper, a direct self-control strategy for reducing the inverter losses is presented and validated.
