چکیده
An induction machine and its associated DC/AC converter together with the PWM feedforward control strategy are described within a hybrid modeling formalism. Depending on the current speed level diierent control strategies have to be applied. To switch between these diierent modes a particular switching procedure is developed. In a rst step, for validation of this method the features of diierent hybrid simulation tools are investigated. R esum e: La machine asynchrone et la commande rapproch ee (MLI) envisag ees pour l'alimentation de la nouvelle g en eration du TGV sont expos es dans le formalisme des syst emes dynamiques hybrides. Les MLI dii erentes sont n ecessaires pour atteindre des hautes fr equences souhait ees. Une solution au probl eme du basculement est alors evoqu ee. AAn de valider les m ethodes elabor ees quelques logiciels de simulation hy-bride sont d'abord test es et classii es.

design tools and collaborative ideation
This paper presents the results of a comparative study between traditional analogue tools (sketches and physical models), a CAD software (digital) and a hybrid tool (digital and analogue) that allows immersive freehand sketching and model making (the Hybrid Ideation Space), in order to assess their respective abilities to support collaborative ideation. By comparing these tools, we were able to...
متن کاملExploration of a plant architecture database with the AMAPmod software illustrated on an apple tree hybrid family
This paper describes the constitution and the statistical exploration of a plant architecture database using the AMAPmod system. In AMAPmod, plant architectures are represented by a formal model, called MTG, which is the central data structure of the system. A dedicated querying language AML enables the user to access plant architecture data with efficient built-in primitives. By combining thes...

Tools available to search information on the Web have a general approach, ignoring a user’s characteristics, and this limits the quality of the results that they may provide. The AIRA system presented here uses document references gathered by the user to build a profile to describe him, and it uses this profile to interpret and filter the results retrieved by Web search engines. In this article...

197 A versatile computer system with interactive graphics is being used for the numerical modelling of antennas on aircraft. The POP-I I based system has been interfaced into an extensive computer network and to laboratory experiments, providing several stand-alone and terminal modes of operation supported by corresponding software. The special man-computer relationship made possible, overcomes...
متن کاملUn Caml Light Distribué
Résumé. Dans cet article nous proposons une extension du langage fonctionnel Caml Light appelé ACCL (pour A Concurrent Caml Light) dont le but est de combiner les paradigmes de programmation impérative, fonctionnelle, de concurrence et de distribution dans un seul langage de programmation. Pour l’extension concurrente de Caml Light nous proposons quelques primitives avec une sémantique très sim...
