Available in PDF, EPUB and Kindle. Book excerpt: UN SYSTEME DYNAMIQUE EST DIT HYBRIDE (SDH) LORSQUE DES VARIABLES DISCRETES ET CONTINUES INTERAGISSENT. LE DEVELOPPEMENT DE METHODES SPECIFIQUES DE REPRESENTATION, D'ANALYSE ET DE COMMANDE S'IMPOSE POUR PRENDRE EN COMPTE LA COMPLEXITE DE CES SYSTEMES. UNE CLASSIFICATION DES SDH EST PROPOSEE EN FONCTION DES TYPES DE PHENOMENES HYBRIDES CONSIDERES : COMMUTATIONS DE MODELE CONTROLEES OU AUTONOMES, SAUTS DU VECTEUR D'ETAT CONTROLES OU AUTONOMES. DES PROBLEMES DE COMMANDE SONT ENSUITE POSES ET ANALYSES POUR CHAQUE CLASSE PRESENTEE. LA RECHERCHE D'UNE COMMANDE OPTIMALE EST POSEE COMME UN PROBLEME DE MINIMISATION D'UN CRITERE D'ECART ENTRE UNE TRAJECTOIRE CALCULEE ET UNE TRAJECTOIRE DESIREE. UNE METHODE DE DESCENTE EST APPLIQUEE DANS CHAQUE CAS ; ELLE FAIT APPEL A L'EXPRESSION DU GRADIENT DU CRITERE. CE DERNIER EST CALCULE A PARTIR DE LA SOLUTION D'UN SYSTEME ADJOINT. ON MONTRE COMMENT CALCULER CE SYSTEME ADJOINT EN ADAPTANT AUX CAS CONSIDERES LES PRINCIPES GENERAUX DU CALCUL DES VARIATIONS. C'EST AINSI QU'APPARAISSENT DES DISCONTINUITES SUR L'ETAT ADJOINT, DONT ON DONNE LES EXPRESSIONS EXPLICITES. CES DISCONTINUITES SE RETROUVENT SUR LA COMMANDE CALCULEE. LA MINIMISATION DU CRITERE EST REALISEE D'ABORD SANS CONTRAINTES PUIS AVEC DES CONTRAINTES DE TYPE BORNE SUR LA COMMANDE ET SUR SA DERIVEE, EN METTANT EN UVRE LA METHODE D'UZAWA. LE PROBLEME DE COMMANDE PAR RETOUR D'ETAT EST ABORDE POUR LES CLASSES DE SDH A COMMUTATIONS DE MODELE CONTROLEES ET AUTONOMES. CECI CONDUIT A LA RESOLUTION D'EQUATIONS DE RICCATI. CHAQUE CAS ETUDIE EST ILLUSTRE PAR UNE MISE EN UVRE NUMERIQUE QUI PERMET DE JUGER DE L'EFFICACITE DE LA METHODE PROPOSEE, EN TERMES DE PRECISION ET DE TEMPS DE CALCUL, ET DE CONCLURE A LA POSSIBILITE DE COMMANDER DES SDH PAR CES METHODES.

Download or read book Byzantium After Byzantium written by Nicolae Iorga and published by Center For Romanian Studies. This book was released on 2023-01-24 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in French in 1935, the author's formula Byzantium after Byzantium defines several centuries of world history. Iorga points out the great contributions of Byzantine civilization to the Western world, especially during the Renaissance. He demonstrates that Byzantium survived through its people and local autonomies, as well as through its exiles--clerics, scholars, merchants, and political officials. One of the most important expressions of this was found in the Romanian principalities where Greeks from the Phanar district of Istanbul played a major role in Romanian political life, defining an entire period of Romanian history--the Phanariot Period. They continued the Byzantine ideas, aspirations, education, and way of life. All of this allows us to speak of a Byzantium after Byzantium.
