This book was released on 2004 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: La présente thèse réalise une analyse des nouvelles techniques de commande adaptative non linéaire pour éliminer les principales restrictions des actuelles synthèses. Dans ce cadre théorique le travail est abordé à travers trois problématiques de première importance: les paramétrisations non linéaires, la commande adaptative des systèmes port-controlled Hamiltonian et le problème de détectabilité.Dû aux complexités des systèmes paramètrisés non-linéairement, la recherche des lois de commande adaptative pour plantes non--linéaires générales est difficile, et normalement aboutit à des schémas conservatifs. De ce fait, le travail présent considère la classe de systèmes de réaction ou les non-linéarities apparaissent sous la forme de quotients des polynômes à la sortie du procès avec des paramètres inconnus. Le concept de système de réactions fait référence a une ample classe de systèmes dynamiques non--linéaires qui on été utilisés longtemps en tant qu'outils pratiques pour une meilleure compréhension des problèmes de génie en divers champs tels que le génie chimique, biomédical, biotechnologie, écologie, etc.Contributions de la Thèse1.Analyse et contrôle non linéaire robuste des systèmes de réaction.2.Commande adaptative d'une classe de systèmes non-linéaires avec paramétrisations non linéaires3.Au delà du problème de détectabilité dans la commande adaptative4.Commande adaptative non--linéaire des systèmes hamiltoniens.

This book was released on 2014-02 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage se fixe comme objectif la commande des systemes non lineaires en utilisant la technique backstepping . Dans notre tentative de rapprocher le lecteur de cette strategie de commande, nous nous sommes atteles a mettre en relief ce qu'il y a de fondamental. Ce livre explique les differentes methodes de commande des differents types de systemes non lineaires (non adaptative- adaptative - avec observateur). Sous le terme de backstepping, on regroupe un certain nombre de modeles de systemes non lineaires dont l'intention est de faire leur commande adaptative. Cette derniere a connu un grand interet a la fin des annees 80. Objectifs: Contribuer aux fondements de la theorie du controle des systemes non lineaires. Developper et analyser globalement la technique (methode) de commande. Appliquer cette methode ou technique sur des procedes physiques. Deduire une conclusion generale concernant cette technique. Presentation du travail: La technique du backstepping, adaptee aux systemes triangulaires inferieurs, est une methode de commande recursive basee sur la fonction de Lyapunov. Cette derniere est un outil bien connu pour l'etude de la stabilite des systemes"
Download or read book Convertisseurs et lectronique de puissance written by Michel Pinard and published by Dunod. This book was released on 2007-04-18 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage dresse un large panorama de l'électronique de puissance : aspects fondamentaux et résultats expérimentaux, équipements et matériels, outils de conception et mise en oeuvre en milieu industriel. C'est dans cet esprit résolument pragmatique que sont ainsi présentés : les systèmes électroniques de commande, créateurs et transmetteurs, analogique et numérique ; les différents types de convertisseurs, leurs principes de fonctionnement et leurs comportements dans les conditions idéales puis réelles ; leurs performances, grâce notamment à la souplesse des systèmes de commande, mais aussi leurs fragilités (en particulier en régime transitoire) ; les outils logiciels (SIMULINK, PSpice et LabVIEW) à même d'accroître la connaissance de leurs comportements et la mise au point de systèmes plus performants. En annexes sont par ailleurs décrits plus en détail les outils mathématiques et informatiques de l'électronique de puissance. De très nombreux exemples et études de cas illustrent le propos du livre, ainsi véritable outil de référence, de travail et d'apprentissage pour tous les professionnels ou futurs professionnels de l'électrotechnique et de l'automatique : ingénieurs, techniciens et élèves ingénieurs, mais aussi étudiants en 3e cycle.

Book excerpt: CE TRAVAIL SE SITUE DANS LE CADRE DE L'APPLICATION DE LA COMMANDE ADAPTATIVE A CERTAINS SYSTEMES NON LINEAIRES, PLUS PARTICULIEREMENT AUX SYSTEMES ROBOTIQUES ET AUX ALTERNATEURS. NOUS NOUS SOMMES INTERESSES A DES METHODES DE LA COMMANDE ADAPTATIVE QUI PEUVENT ETRE REELLEMENT EXPLOITEES POUR LES PROCESSUS INDUSTRIELS TOUT EN PRESERVANT LA STABILITE DU SYSTEME. NOUS PRESENTONS LA PARAMETRISATION MINIMALE POUR LE SYSTEME ROBOTIQUE. CECI NOUS PERMET DE REDUIRE LE NOMBRE DE CALCUL A LA METHODE DU REGROUPEMENT DES PARAMETRES QUI ELIMINE CEUX N'AFFECTANT PAS LA DYNAMIQUE DU ROBOT. SUITE A UNE ANALYSE COMPLETE DE LA MATRICE QUI DETERMINE LA RICHESSE DE LA TRAJECTOIRE DU ROBOT, NOUS AVONS PROUVE QUE LA CONVERGENCE DES PARAMETRES MINIMAUX EST PLUS FACILEMENT OBTENUE QUE CELLE DES PARAMETRES NON MINIMAUX. ENFIN, LA DERNIERE PARTIE DE CE TRAVAIL DONNE UNE APPLICATION REELLE DE LA COMMANDE ADAPTATIVE EFFECTUEE DANS UNE USINE DE FABRICATION DES CONTROLEURS D'ALTERNATEUR. EN EFFET, APRES LA COMPARAISON DES PLUSIEURS METHODES, NOUS EN AVONS RETENU UNE QUI GARDE AUSSI BIEN LA STABILITE DU SYSTEME QUE LA QUANTITE DU CALCUL PERMETTANT D'IMPLANTER CETTE METHODE. DES TESTS REALISES SUR SITE NOUS MONTRENT UNE NETTE AMELIORATION DE LA PERFORMANCE DU SYSTEME

Download or read book The Geo Doc written by Mark Terry and published by Springer Nature. This book was released on 2020-02-03 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces a new form of documentary film: the Geo-Doc, designed to maximize the influential power of the documentary film as an agent of social change. By combining the proven methods and approaches as evidenced through historical, theoretical, digital, and ecocritical investigations with the unique affordances of Geographic Information System technology, a dynamic new documentary form emerges, one tested in the field with the United Nations. This book begins with an overview of the history of the documentary film with attention given to how it evolved as an instrument of social change. It examines theories surrounding mobilizing the documentary film as a communication tool between filmmakers and policymakers. Ecocinema and its semiotic storytelling techniques are also explored for their unique approaches in audience engagement. The proven methods identified throughout the book are combined with the spatial and temporal affordances provided by GIS technology to create the Geo-Doc, a new tool for the activist documentarian.

Download or read book Mother Work written by Molly Ladd-Taylor and published by University of Illinois Press. This book was released on 2022-10-17 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Early in the twentieth century, maternal and child welfare evolved from a private family responsibility into a matter of national policy. Molly Ladd-Taylor explores both the private and public aspects of child-rearing, using the relationship between them to cast new light on the histories of motherhood, the welfare state, and women's activism in the United States. Ladd-Taylor argues that mother-work, "women's unpaid work of reproduction and caregiving," motivated women's public activism and "maternalist" ideology. Mothering experiences led women to become active in the development of public health, education, and welfare services. In turn, the advent of these services altered mothering in many ways, including the reduction of the infant mortality rate.
Download or read book Prairie Fairies written by Valerie J. Korinek and published by University of Toronto Press. This book was released on 2018-01-01 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prairie Fairies draws upon a wealth of oral, archival, and cultural histories to recover the experiences of queer urban and rural people in the prairies. Focusing on five major urban centres, Winnipeg, Saskatoon, Regina, Edmonton, and Calgary, Prairie Fairies explores the regional experiences and activism of queer men and women by looking at the community centres, newsletters, magazines, and organizations that they created from 1930 to 1985.? Challenging the preconceived narratives of queer history, Valerie J. Korinek argues that the LGBTTQ community has a long history in the prairie west, and that its history, previously marginalized or omitted, deserves attention. Korinek pays tribute to the prairie activists and actors who were responsible for creating spaces for socializing, politicizing, and organizing this community, both in cities and rural areas. Far from the stereotype of the isolated, insular Canadian prairies of small towns and farming communities populated by faithful farm families, Prairie Fairies historicizes the transformation of prairie cities, and ultimately the region itself, into a predominantly urban and diverse place.
Download or read book Food Fray written by Lisa H. WEASEL Ph.D. and published by AMACOM Div American Mgmt Assn. This book was released on 2008-12-10 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than ten years ago, the first genetically modified foods took their place on the shelves of American supermarkets. But while American consumers remained blissfully unconcerned with the new products that suddenly filled their kitchens, Europeans were much more wary of these “Frankenfoods.” When famine struck Africa in 2002, several nations refused shipments of genetically modified foods, fueling a controversy that put the issue on the world's political agenda for good. In Food Fray, esteemed molecular biologist Dr. Lisa H. Weasel brings readers into the center of this debate, capturing the real-life experiences of the scientists, farmers, policymakers and grassroots activists on the front lines. Here she combines solid scientific knowledge and a gripping narrative to tell the real story behind the headlines and the hype. Seminal and cutting-edge, Food Fray enlightens and informs and will allow readers to make up their own minds about one of the most important issues facing us today.
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.
