LE TRAVAIL PRESENTE DANS CE MEMOIRE DE THESE EST CONSACRE A L'ANALYSE ET AU CONTROLE A L'AIDE DE LA LOGIQUE FLOUE D'UN PROCEDE BIOLOGIQUE DE DEPOLLUTION. LE PROCEDE CONSIDERE EST UN REACTEUR DE DIGESTION ANAEROBIE A LIT FLUIDISE TRAITANT DES VINASSES DE VIN. MALGRE SES BONNES PERFORMANCES, CE PROCEDE PEUT ETRE FACILEMENT DESTABILISE PAR LES VARIATIONS DE LA CHARGE POLLUANTE ENTRANTE, IL EST DONC NECESSAIRE DE LE CONTROLER. LE MANQUE D'INFORMATION EN LIGNE SUR L'ACTIVITE BACTERIENNE REND DIFFICILE LA MISE EN OEUVRE D'ALGORITHME DE COMMANDE CLASSIQUE EN AUTOMATIQUE. L'UTILISATION DE LA LOGIQUE FLOUE PERMET DE PALLIER CE MANQUE D'INFORMATION, EN INTEGRANT DANS L'ALGORITHME DE COMMANDE, L'EXPERTISE HUMAINE ACQUISE SUR LA CONDUITE DE CES PROCEDES. L'OBJECTIF DU CONTROLE EST DE MAINTENIR LE REACTEUR EN UN POINT DE FONCTIONNEMENT TOUT EN LUI ASSURANT UN BON RENDEMENT D'EPURATION. LE CONTROLE DOIT ETRE BASE SUR DES VARIABLES MESURABLES EN LIGNE ET POUR LESQUELLES IL EXISTE DES CAPTEURS INDUSTRIELS PEU COUTEUX. POUR FACILITER LA MISE AU POINT DU CONTROLEUR FLOU, UN MODELE DE CONNAISSANCE DU PROCEDE, BASE SUR DES BILANS MATIERES A ETE ELABORE ET VALIDE A PARTIR DE RESULTATS EXPERIMENTAUX. NOUS PRESENTONS LA DEMARCHE UTILISEE POUR CONSTRUIRE ET METTRE AU POINT LE CONTROLEUR. IL EST ENSUITE TESTE SUR UN REACTEUR EXPERIMENTAL DE 15 LITRES, PUIS SUR UN PILOTE DE TAILLE SEMI-INDUSTRIELLE DE 150 LITRES. POUR AMELIORER LES PERFORMANCES DU CONTROLE, NOUS AVONS RAJOUTE DES VARIABLES. POUR LES INTEGRER FACILEMENT, NOUS AVONS HIERARCHISE LA STRUCTURE DU CONTROLEUR. CETTE NOUVELLE STRUCTURE EST TESTEE ET VALIDEE SUR LES DEUX PROCEDES. LE CONTROLEUR FLOU PRESENTE L'AVANTAGE D'ETRE FACILEMENT ADAPTABLE A D'AUTRES PROCEDES BIOLOGIQUES DE DEPOLLUTION TRAITANT DES EFFLUENTS DIFFERENTS.

CETTE THESE PORTE SUR LE CONTROLE DES PROCEDES BIOLOGIQUES DE DEPOLLUTION DES EAUX. LES NORMES DE REJETS ET LEUR PROCHAIN RENFORCEMENT IMPLIQUENT UNE MAITRISE ACCRUE DES MOYENS DE TRAITEMENT. POUR Y PARVENIR, LE RECOURS AUX THEORIES DE L'AUTOMATIQUE SEMBLE INELUCTABLE. DEUX AXES DE RECHERCHES, PERMETTANT D'AMELIORER SIGNIFICATIVEMENT LES PERFORMANCES D'UN SYSTEME DE CONTROLE D'UN PROCEDE BIOLOGIQUE ONT ETE IDENTIFIES. . LE PREMIER CONSISTE EN UNE CARACTERISATION PLUS FINE DES SYSTEMES A CONTROLER, ET EN PARTICULIER DES PERTURBATIONS INTERNES ET/OU EXTERNES POUVANT INTERVENIR SUR LE PROCEDE. AINSI, APRES AVOIR REDEFINI LE PROBLEME DE COMMANDE DE CE TYPE DE PROCEDES, NOUS PROPOSONS UNE STRATEGIE DE COMMANDE DITE ACCOMMODANTE DE PERTURBATIONS. CETTE APPROCHE EST TESTEE EN SIMULATION POUR LA COMMANDE D'UN PROCEDE DE NITRIFICATION ET SUR PROCEDE REEL POUR LA REGULATION D'UN PROCEDE DE METHANISATION EN LIT FLUIDISE SOUMIS A DES PERTURBATIONS INTERNES ET EXTERNES. . LE DEUXIEME AXE DE RECHERCHES EST ORIENTE VERS L'INTEGRATION DES SYSTEMES. CETTE METHODOLOGIE PERMET, AU TRAVERS D'UN PROBLEME D'OPTIMISATION, DE PRENDRE EN COMPTE LES OBJECTIFS DE COMMANDE SIMULTANEMENT AVEC LE CALCUL DES PARAMETRES PHYSIQUES DU PROCEDE ET CE, AU STADE INITIAL DE LA CONCEPTION. DANS CETTE OPTIQUE, NOUS DEVELOPPONS LA THEORIE DU DESIGN ECONOMIQUE DES PROCEDES QUI NOUS PERMET D'INTEGRER LA SYNTHESE D'UN REGULATEUR ACCOMMODANT ET LA RECHERCHE DE LA CONFIGURATION OPTIMALE DES ACTIONNEURS-CAPTEURS DU SYSTEME CONSIDERE.

A Frequency Dictionary of French is an invaluable tool for all learners of French, providing a list of the 5000 most frequently used words in the language. Based on a 23-million-word corpus of French which includes written and spoken material both from France and overseas, this dictionary provides the user with detailed information for each of the 5000 entries, including English equivalents, a sample sentence, its English translation, usage statistics, and an indication of register variation. Users can access the top 5000 words either through the main frequency listing or through an alphabetical index. Throughout the frequency listing there are thematically-organized lists of the top words from a variety of key topics such as sports, weather, clothing, and family terms. An engaging and highly useful resource, the Frequency Dictionary of French will enable students of all levels to get the most out of their study of French vocabulary. Former CD content is now available to access at www.routledge.com/9780415775311 as support material. Designed for use by corpus and computational linguists it provides the full text in a format that researchers can process and turn into suitable lists for their own research work.

The Handbook of Nonlinear Partial Differential Equations is the latest in a series of acclaimed handbooks by these authors and presents exact solutions of more than 1600 nonlinear equations encountered in science and engineering--many more than any other book available. The equations include those of parabolic, hyperbolic, elliptic and other types, and the authors pay special attention to equations of general form that involve arbitrary functions. A supplement at the end of the book discusses the classical and new methods for constructing exact solutions to nonlinear equations. To accommodate different mathematical backgrounds, the authors avoid wherever possible the use of special terminology, outline some of the methods in a schematic, simplified manner, and arrange the equations in increasing order of complexity.

This book is the first easy-to-read text on nonsmooth optimization (NSO, not necessarily differentiable optimization). Solving these kinds of problems plays a critical role in many industrial applications and real-world modeling systems, for example in the context of image denoising, optimal control, neural network training, data mining, economics and computational chemistry and physics. The book covers both the theory and the numerical methods used in NSO and provide an overview of different problems arising in the field. It is organized into three parts: 1. convex and nonconvex analysis and the theory of NSO; 2. test problems and practical applications; 3. a guide to NSO software. The book is ideal for anyone teaching or attending NSO courses. As an accessible introduction to the field, it is also well suited as an independent learning guide for practitioners already familiar with the basics of optimization.
