Book excerpt: LE TRAVAIL PRESENTE DANS CETTE THESE APPROFONDIT CERTAINS ASPECTS LIES A LA COMMANDE DES SYSTEMES HYBRIDES DYNAMIQUES AUTOPILOTES. NOUS AVONS MIS EN OEUVRE DEUX DISPOSITIFS POUR ILLUSTRER NOTRE TRAVAIL : L'ONDULEUR A RESONANCE SERIE ET LE MOTEUR A RELUCTANCE VARIABLE A DOUBLE SAILLANCE. NOUS AVONS MIS EN EVIDENCE ET UTILISE LEURS PROPRIETES COMMUNES POUR DEVELOPPER DES COMMANDES ANALOGIQUES SIMPLES ET ECONOMIQUES. NOUS AVONS CONCU ET REALISE CES COMMANDES PAR ANALOGIE FORMELLE. CES SYSTEMES PEUVENT SE SYNCHRONISER SUR UN SIGNAL EXTERNE DE FREQUENCE DONNEE. NOUS AVONS RELEVE LES CARACTERISTIQUES DE SYNCHRONISATION DU MRVDS ET DE L'ONDULEUR A RESONANCE ET NOUS AVONS UTILISE CES PROPRIETES POUR LES COMMANDER. NOUS AVONS ENSUITE DEVELOPPE DES PRINCIPES DE COMMANDE PERMETTANT D'OPTIMISER LE COMPORTEMENT DE L'ONDULEUR SUR DES CRITERES ELECTROTECHNIQUES. NOUS AVONS MODELISE CE SYSTEME ET NOUS AVONS MONTRE QUE DANS CE CAS, LE MODELE ECHANTILLONNE N'EST PAS LINEARISABLE. POUR LE MRVDS, NOUS AVONS DEUX APPLICATIONS DIFFERENTES : UNE APPLICATION GRANDE VITESSE ET UNE APPLICATION FAIBLE VITESSE. DANS LE CAS DE L'APPLICATION BASSE VITESSE, NOUS AVONS MONTRE QUE LE BRUIT ACOUSTIQUE ETAIT DU A UN PHENOMENE DE BATTEMENTS ENTRE LES HARMONIQUES DE LA TENSION REDRESSEE ET LA FREQUENCE DE ROTATION. NOUS AVONS UTILISE LES PROPRIETES DE SYNCHRONISATIONS DU MRVDS POUR ELIMINER CES BATTEMENTS. NOUS AVONS EGALEMENT DEVELOPPE UN DISPOSITIF DE DEMARRAGE AUTOMATIQUE PERMETTANT DE SE PLACER DANS LES ZONES DE SYNCHRONISATION. POUR L'APPLICATION GRANDE VITESSE, NOUS AVONS MONTRE QU'IL EST POSSIBLE DE COMMANDER LA VITESSE DU MOTEUR EN AGISSANT SUR L'ANGLE D'AVANCE GRACE A UNE CONSIGNE DE TENSION. NOTRE DEMARCHE A ETE DE SYNTHETISER LES PROPRIETES COMMUNES DE SYSTEMES TRES DIFFERENTS, CARACTERISER LES MODES DE FONCTIONNEMENT, MODELISER, SIMULER ET VERIFIER EXPERIMENTALEMENT LA VALIDITE DES PRINCIPES DE COMMANDE PROPOSES.
Book Synopsis Common Energetic Macroscopic Representation and Unified Control Structure for Different Hybrid Electric Vehicles by : Keyu Chen
Download or read book Common Energetic Macroscopic Representation and Unified Control Structure for Different Hybrid Electric Vehicles written by Keyu Chen and published by . This book was released on 2010 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le domaine du transport, l'un des plus grands secteurs d'énergie, doit affronter des défis importants tels que la sécurité énergétique, le changement climatique et les problèmes de la pollution. Pour répondre à cela, les Véhicules Électriques et Hybrides (VEHs) deviennent une option intéressante. L'un des problèmes clés liées au développement des VEHs est la conception de la commande de ce type de système complexe, lequel est composé de plusieurs sources et sous-systèmes. En utilisant la Représentation Énergétique Macroscopique (REM) qui est une représentation graphique basée sur l'énergie, une structure de commande peut être déduire directement par inversion du modèle. L'objectif de cette thèse est d'établir une REM commune capable de décrire différentes architectures de VEHs. A partir de cette REM, une structure de commande générale est obtenue. Cette structure de commande peut être utilisée pour l'étude de VEH série, parallèle et mixte, en changent seulement différents valeurs de paramètres. Cette REM permet de mieux comprendre les flux de puissance principaux des différent VEHs. En utilisant une approche descendante, la modélisation et la commande des différent VEHs ont été réalisées de manière générale, même si ces VEHs peuvent être très différents les uns des autres en termes de structure. Le temps requis pour la conception de la commande peut être ainsi considérablement réduit. Qui plus est, avec la même structure de commande, les différents VEHs peuvent être comparés plus facilement. La structure commune a été validée expérimentalement sur un émulateur de véhicule hybride série. Différentes gestions énergétiques plus efficaces de VEHs pourraient être développées et comparées. De ce fait, le coût de fabrication, la consommation de carburant et l'émission de CO2 peuvent être réduites.

Book Synopsis In-Flight Simulators and Fly-by-Wire/Light Demonstrators by : Peter G. Hamel
Download or read book In-Flight Simulators and Fly-by-Wire/Light Demonstrators written by Peter G. Hamel and published by Springer. This book was released on 2017-03-15 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers the first complete account of more than sixty years of international research on In-Flight Simulation and related development of electronic and electro-optic flight control system technologies (“Fly-by-Wire” and “Fly-by-Light”). They have provided a versatile and experimental procedure that is of particular importance for verification, optimization, and evaluation of flying qualities and flight safety of manned or unmanned aircraft systems. Extensive coverage is given in the book to both fundamental information related to flight testing and state-of-the-art advances in the design and implementation of electronic and electro-optic flight control systems, which have made In-Flight Simulation possible. Written by experts, the respective chapters clearly show the interdependence between various aeronautical disciplines and in-flight simulation methods. Taken together, they form a truly multidisciplinary book that addresses the needs of not just flight test engi neers, but also other aeronautical scientists, engineers and project managers and historians as well. Students with a general interest in aeronautics as well as researchers in countries with growing aeronautical ambitions will also find the book useful. The omission of mathematical equations and in-depth theoretical discussions in favor of fresh discussions on innovative experiments, together with the inclusion of anecdotes and fascinating photos, make this book not only an enjoyable read, but also an important incentive to future research. The book, translated from the German by Ravindra Jategaonkar, is an extended and revised English edition of the book Fliegende Simulatoren und Technologieträger , edited by Peter Hamel and published by Appelhans in 2014.
Book Synopsis Masters Theses in the Pure and Applied Sciences by : Wade H. Shafer
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer. This book was released on 1985-03 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 28 (thesis year 1 983) a total of 10,661 theses titles from 26 Canadian and 197 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 28 reports theses submitted in-1983, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Synopsis The Cambridge Aerospace Dictionary by : Bill Gunston
Download or read book The Cambridge Aerospace Dictionary written by Bill Gunston and published by Cambridge University Press. This book was released on 2011-02-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Aerospace Dictionary is an authoritative and accessible reference useful to scholars and enthusiasts alike. This dictionary is an essential tool for professionals involved in the aerospace industry and flight, and for anyone who must read and understand the technical literature of the aerospace industry and about specific air and space craft. It is also an ideal reference for engineering and physics students encountering a subject replete with technical jargon and acronyms. Bill Gunston, one of the most widely read and respected aviation writers, has added more than 5,000 new terms and acronyms to this carefully updated volume. Terms used in the dictionary reflect the diverse and international nature of the aerospace industry and include brief explanations of aerospace materials and organizations. Gunston has scrupulously avoided terms specific to manufacturers, airlines, and armed forces in an effort to encourage clear communication and understanding among professionals.
Book Synopsis Space-Age Acronyms by : Reta C. Moser
Download or read book Space-Age Acronyms written by Reta C. Moser and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acronym agglomeration is an affliction of the age, and there are acronym addicts who, in their weakness, find it impossible to resist them. More than once in recent months my peers have cautioned me about my apparent readiness to use not only acronyms, but abbreviations, foreign isms, codes, and other cryptic symbols rather than common, ordinary American words. Many among us, though, either have not received or have chosen to ignore such advice. As a consequence, what we write and speak is full of mystery and confusion. It is then for the reader and listener and for the writer and speaker that Reta C. Moser has compiled this guide. Its effective application to the art of communication is urged. Such use should help avoid many of the misunderstandings involving terminology which occur daily. Although such misunderstandings are certainly crucial in humanistic and social situations, they are often of immediate import and the trigger to disaster in scientific, technical, and political situations. Some 15,000 acronyms and 25,000 definitions are provided (a 50- and 47 -percent increase over the 1964 edition!), with due credit to Miss Moser's diligence in making the compilation and with the acknowledgment that the acronymical phenomenon is very much with us. This edition, like the first, is certain to be of value to writers, librarians, editors, and others who must identify and deal with acronyms.
