Available in PDF, EPUB and Kindle. Book excerpt: CETTE THESE CONCERNE LA ROBUSTESSE DES SYSTEMES NON LINEAIRES. ELLE PROPOSE DEUX METHODES DE SYNTHESE DE LOI DE COMMANDE ROBUSTE ET UNE METHODE D'ANALYSE DE LA ROBUSTESSE. ELLE COMPORTE TROIS PARTIES : LA PREMIERE PRESENTE UNE NOUVELLE FORMULATION DU PROBLEME D'ATTENUATION DES PERTURBATIONS. LA LOI DE COMMANDE EST CARACTERISEE PAR LA SOLUTION D'UNE EQUATION DE TYPE HAMILTON-JACOBI-ISSACS AVEC CONTRAINTES FINALES D'INEGALITE. LA METHODOLOGIE PROPOSEE UTILISE LES TECHNIQUES D'HORIZON GLISSANT. ELLE ABOUTIT A UNE LOI DE STABILISATION ROBUSTE PAR RETOUR D'ETAT DYNAMIQUE DISCONTINU. AFIN DE VALIDER CETTE METHODE, UNE APPROCHE NUMERIQUE POUR RESOUDRE L'EQUATION DE HJI EST DEVELOPPEE CONFORMEMENT A LA THEORIE PROPOSEE. LES IDEES INTUITIVES AINSI QUE L'EFFICACITE DU CALCUL NUMERIQUE ASSOCIE SONT ILLUSTREES PAR UN EXEMPLE DE PENDULE INVERSE SIMPLE ET UN EXEMPLE DE SATELLITE EN MODE DEFAILLANT. LA DEUXIEME PARTIE PROPOSE UN ALGORITHME DE RESOLUTION DU PROBLEME D'OPTIMISATION MIN-MAX. L'ALGORITHME EST MIS EN BOUCLE FERMEE DANS UN SCHEMA A HORIZON GLISSANT. LES SYSTEMES CONSIDERES NE SONT PAS NECESSAIREMENT AFFINES. LES CONTRAINTES SUR LA COMMANDE PEUVENT ETRE PRISES EN COMPTE, MEME SI CES CONTRAINTES DEPENDENT DE L'ETAT. L'APPROCHE PEUT TRAITER LES INCERTITUDES PARAMETRIQUES ET LES PERTURBATIONS NON STATIONNAIRES. DANS LE DOMAINE DES PROCEDES BATCH LA METHODE ABOUTIT A DES RESULTATS TRES INTERESSANTS. QUANT AU DOMAINE DE LA MACHINE ASYNCHRONE, LES RESULTATS OBTENUS, BIEN QU'ILS SOIENT PRELIMINAIRES, MONTRENT L'APPORT INEDIT DE CETTE METHODE, SURTOUT EN CE QUI CONCERNE LES QUESTIONS PRIMORDIALES DE LA ROBUSTESSE ET DU REJET D'HARMONIQUES. LA TROISIEME PARTIE ILLUSTRE L'APPLICATION DE LA THEORIE DU GAP METRIQUE A L'ANALYSE DE LA ROBUSTESSE DES SYSTEMES DYNAMIQUES. LE CONTEXTE DE LA COMMANDE$H-ISINFTY$EST CONSIDERE COMME EXEMPLE. L'ETUDE N'ABOUTIT PAS A UNE NOUVELLE CONCLUSION CONCERNANT LA COMMANDE$H-ISINFTY$, ELLE MONTRE, NEANMOINS, LE NOUVEL OUTIL D'ANALYSE DE LA ROBUSTESSE.

Available in PDF, EPUB and Kindle. Book excerpt: Le travail de la thèse traite le problème de suivi de trajectoires des systèmes non linéaires incertains,dont le modèle nominal est construit à l'aide d'un système flou TS (Takagi-Sugeno) de type-2. Cedernier, exploite les modèles locaux du système obtenus par linéarisation autour de certains pointsde fonctionnement. La commande développée est basée sur les modes glissants d'ordre deux avecSuper-Twisting. Nous avons proposé deux systèmes flous type-2 adaptatifs, qui ont comme uniqueentrée la surface de glissement, pour résoudre le problème du calcul de la valeur optimale des gainsde la commande. Des résultats de simulation ont permis de comparer les performances de l'approcheproposée avec la méthode classique. Ensuite, nous avons introduit le concept de l'intégral sliding modepour imposer à priori le temps d'arrivée sur la surface de glissement. Les approches proposées sontgénéralisées aux cas des systèmes multivariables. Plusieurs résultats par simulation et implémentationen temps réel sont présentés pour illustrer les performances des approches développées.

Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse étudie l'approche LPV pour la commande robuste des systèmes non linéaires. Son originalité est de proposer pour la première fois un cadre rigoureux permettant de résoudre efficacement des problèmes de synthèse non linéaire. L'approche LPV a été proposée comme une extension de l'approche H-infini dans le contexte des systèmes LPV (« Linéaires à Paramètres Variant dans le temps »), voire non linéaires. Quoique prometteuse, cette approche pour la commande des systèmes non linéaires restait peu utilisée. En effet, au-delà même de certaines limitations théoriques, la nature des solutions obtenues semblait inadéquate. Cette question ouverte est notre point de départ. Nous montrons tout d'abord que la faible variation des correcteurs constatée est due avant tout à la nature du schéma informationnel utilisé traditionnellement lors de la synthèse LPV, et que sous des hypothèses raisonnables, le cadre LPV peut permettre de recouvrir des stratégies de type « linéarisation par bouclage ». Ce point étant acquis, une deuxième difficulté réside dans l'obtention effective de correcteurs non linéaires donnant des garanties de performance. Nous proposons un cadre rigoureux permettant de résoudre efficacement un problème de synthèse incrémentale pondérée, par la résolution d'un problème LPV associé à un schéma informationnel spécifique compatible avec celui identifié dans la première partie. Cette étude et son aboutissement à la définition d'un cadre formel et d'une procédure complète d'obtention de correcteurs, incluant des méthodes de réduction de complexité, donnent des arguments puissants en faveur de l'approche LPV pour la commande robuste de systèmes non linéaires.

Download or read book Elements of Structural Syntax written by Lucien Tesnière and published by John Benjamins Publishing Company. This book was released on 2015-02-11 with total page 782 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume appears now finally in English, sixty years after the death of its author, Lucien Tesnière. It has been translated from the French original into German, Spanish, Italian, and Russian, and now at long last into English as well. The volume contains a comprehensive approach to the syntax of natural languages, an approach that is foundational for an entire stream in the modern study of syntax and grammar. This stream is known today as dependency grammar (DG). Drawing examples from dozens of languages, many of which he was proficient in, Tesnière presents insightful analyses of numerous phenomena of syntax. Among the highlights are the concepts of valency and head-initial vs. head-final languages. These concepts are now taken for granted by most modern theories of syntax, even by phrase structure grammars, which represent, in a sense, the opposite sort of approach to syntax from what Tesnière was advocating. Now Open Access as part of the Knowledge Unlatched 2017 Backlist Collection.
Download or read book Renewable Energy for Smart and Sustainable Cities written by Mustapha Hatti and published by Springer. This book was released on 2018-11-23 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book features cutting-edge research presented at the second international conference on Artificial Intelligence in Renewable Energetic Systems, IC-AIRES2018, held on 24–26 November 2018, at the High School of Commerce, ESC-Koléa in Tipaza, Algeria. Today, the fundamental challenge of integrating renewable energies into the design of smart cities is more relevant than ever. While based on the advent of big data and the use of information and communication technologies, smart cities must now respond to cross-cutting issues involving urban development, energy and environmental constraints; further, these cities must also explore how they can integrate more sustainable energies. Sustainable energies are a major determinant of smart cities’ longevity. From an environmental and technological standpoint, these energies offer an optimal power supply to the electric network while creating significantly less pollution. This requires flexibility, i.e., the availability of supply and demand. The end goal of any smart city is to improve the quality of life for all citizens (both in the city and in the countryside) in a way that is sustainable and respectful of the environment. This book encourages the reader to engage in the preservation of our environment, every moment, every day, so as to help build a clean and healthy future, and to think of the future generations who will one day inherit our planet. Further, it equips those whose work involves energy systems and those engaged in modelling artificial intelligence to combine their expertise for the benefit of the scientific community and humanity as a whole.
Download or read book Conscripts and Deserters written by Alan I. Forrest and published by Oxford University Press, USA. This book was released on 1989 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Between the outbreak of war with Austria in 1792 and Napoleon's final debacle in 1814, France remained almost continously at war, recruiting in the process some two to three million frenchmen--a level of recruitment unknown to previous generations and widely resented as an attack on the liberties of rural communities. Forrest challenges the notion of a nation heroically rushing to arms by examining the massive rates of desertion and avoidance of service as well as their consequences on French society--on military campaigns and the morale of armies, on political opinion at home, on the social fabric of local villages, and on the Napoleonic dream of bringing about a coherent and centralized state.
