Download or read book Electrical Actuators written by Bernard de Fornel and published by John Wiley & Sons. This book was released on 2013-03-04 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: The different chapters of this book cover a large range of information regarding electrical actuators, including: synchronous and asynchronous machine modeling in order to measure and identify offline and online parameters using modern optimization methods; identification in real time of parameters with Luenberger filter and the extended Kalman filter; estimation of non-measurable variables, first by linear estimates and observers, then by lower observers. Robustness is a very problematic issue, as well, which is fully explored in a chapter dedicated to the subject. Finally, the estimate of non-measurable mechanical variables is particularly dealt with: estimate of load moment, then observation of the positioning of a command without mechanical sensor. The conditions to measure variables and real implementation of numerical algorithms are also examined with particular attention.

Download or read book Agricultural English written by Georgeta Raţă and published by Cambridge Scholars Publishing. This book was released on 2012-04-25 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural English is a collection of essays on the English of Agriculture. The approach is a linguistic one: the different aspects of the English used in the field of agriculture (agricultural practices, agricultural systems) and in some fields related to agriculture (agricultural zoology, agri-tourism, biology, botany, ecology, entomology, gastronomy, land measurement, plant pathology, zoology) are analysed from a morphological (combination, derivation), syntactical (nominal phrases, verbal phrases), lexical and lexicographical, semantic (homonymy, semantic fields, synonymy, terminology), pragmatic (academic discourse, idiom, metaphor), etymological (etymon, Latin heritage), and contrastive (English–Croatian, English–French, English–German, English–Romanian, Romanian–English) points of view. The book will appeal to agriculturists, animal breeders, professors, researchers, students, and translators from Croatian-, English-, French-, German-, and Romanian-speaking countries, active in their own countries or abroad. The types of academic readership it would appeal to include academic teaching staff, researchers and students in the fields of agriculture and related fields – agricultural zoology, agri-tourism, biology, botany, ecology, entomology, gastronomy, land measurement, plant pathology, and zoology.

Download or read book Real Time Digital Control Applications written by A. Alonso-Concheiro and published by Elsevier. This book was released on 2014-05-23 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: Real Time Digital Control Applications is a compilation of papers presented at the Symposium on Real-Time Digital Control Applications, sponsored by the International Federation of Automatic Control (IFAC) and the International Federation for Information Processing (IFIP), held in Guadalajara, Mexico. The event is organized to provide developing countries with the opportunity to gain insights -- from the sharing of ideas and experiences of experts from around the world to the rapid growth and development of applications of real-time digital control systems, which is considered as the basis of industrial revolution. The book presents and discusses the various scientific, industrial, and technical applications of real-time digital control systems. Applications in power generation, water, metal processing, cement, food, and manufacturing industries are shown. The text also covers applications in robotics, biomedicine, monitoring and failure detection, fuel optimization and heat control, adaptive process control, modeling, and computer software. Industrial engineers, scientists, economists, computer scientists, robotics experts, planners, and technicians will find this book invaluable.

Download or read book La commande lectronique des machines written by Michel Pinard and published by Dunod. This book was released on 2013-08-28 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage permet de maîtriser les bases du contrôle et de la commande des machines électriques. Il est constitué d'une soixantaine de fiches pratiques rassemblées dans huit dossiers thématiques. Ces dossiers abordent successivement les questions des alimentations électriques, des convertisseurs de puissance, des différents types de machines (synchrones ou asynchrones), et des différents modes de commande et d'asservissement. Chaque fiche pose un problème précis et ponctuel et en explique la solution. Dans de nombreux cas, des simulations sur les logiciels tels que PSIM, VisSIM et LabVIEW permettent une approche concrète et opérationnelle des difficultés rencontrées dans la mise au point d'un système de commande.

Book excerpt: La machine asynchrone à vitesse variable, ouvrage en deux volumes, présente le moteur asynchrone, son modèle et son comportement en régime statique ou dynamique, dans son contexte environnemental. Il rassemble la modélisation et l'étude des différentes composantes d'un actionneur électrique : asservissements, organes de mesure, commande numérique et chaînes de puissance [...] Ce deuxième volume étudie l'aspect variation de vitesse du moteur, les notions de la logique floue puis la mesure des signaux et leurs traitements. La commande vectorielle ainsi que diverses stratégies (telles que DTC, FOC, SVM, etc.) sont également présentées. Enfin, l'ouvrage explique les éléments relatifs à la détection d'un défaut d'ordre électrique ou mécanique [source : 4ème de couverture]

This book was released on 2015-01-09 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vue l'interet industriel de la Machine Asynchrone Double Alimentee MADA; sa robustesse et ses applications dans les entrainements a vitesse variable, transfert d'energie dans le domaine des grandes puissances; Plusieurs chercheurs ont contribue au controle de ce processus non-lineaire fortement couple possedant des etats non accessible et non mesurables. La plupart des travaux de recherches proposees dans la litterature font une linearisation du modele par orientation du flux magnetique. Ce livre traite de la commande non lineaire de la MADA sans utiliser les techniques de linearisation en proposant un controle base sur la reconduction d'energie totale de la MADA vers une energie desiree. Un autre axe de recherche entame dans ce livre est le controle hybride flou-passif pour resoudre le probleme de controle des etats non accessibles d'une part et la reduction de fluctuations des reponses de la MADA en regime transitoire d'une autre part. Les resultats obtenus dans ce livre par Notre contribution montrent l'efficacite des commandes proposees surtout en matiere de robustesse vis-a-vis les changements des parametres physiques de la machine MADA."
