Available in PDF, EPUB and Kindle. Book excerpt: LA PLUPART DES TRAVAUX CONCERNANT LA MODELISATION ET LA SIMULATION DES SYSTEMES DYNAMIQUES HYBRIDES TRAITENT L'ASPECT CONTINU ET DISCRET COMME DEUX ENTITES DISTINCTES. DANS CETTE THESE, NOUS UTILISONS UN PARADIGME DE SPECIFICATION UNIQUE POUR L'ETUDE DES SYSTEMES DYNAMIQUES HYBRIDES. NOUS MONTRONS COMMENT CONSTRUIRE UNE SPECIFICATION A EVENEMENTS DISCRETS D'UN SYSTEME DYNAMIQUE SANS IMPOSER LA CONTRAINTE CLASSIQUE SUR LES TRAJECTOIRES D'ENTREES-SORTIES. EN EFFET, LES ABSTRACTIONS A EVENEMENTS DISCRETS DE SYSTEMES DYNAMIQUES IMPOSENT QUE LES TRAJECTOIRES D'ENTREES-SORTIES SONT CONSTANTES PAR MORCEAUX. NOUS AVONS GENERALISE CE TYPE D'ABSTRACTION A TOUTE TRAJECTOIRE POLYNOMIALE CONTINUE PAR MORCEAUX. NOUS DEFINISSONS ALORS UN EVENEMENT COMME UNE VARIATION D'AU MOINS UN DES COEFFICIENTS DU POLYNOME ET L'ORDRE D'UN EVENEMENT COMME LE DEGRE MAXIMUM DU POLYNOME. POUR LES MODELES COMPOSITES, ENCORE APPELES MODELES STRUCTURELS, LA COMMUNICATION ENTRE LES COMPOSANTS S'EFFECTUE PAR L'INTERMEDIAIRE DE PORTS D'ENTREE-SORTIE. NOUS AVONS ETENDU LE CONCEPT DE PORT EN AJOUTANT LA NOTION D'ORDRE (ORDRE DE L'EVENEMENT QUI PEUT ETRE ACCEPTE SUR CE PORT). LE PROBLEME POSE ENSUITE EST DE FAIRE COMMUNIQUER DEUX MODELES POSSEDANT DES PORTS D'ORDRE DIFFERENT AFIN DE SIMULER UN MODELE COMPOSITE. POUR CELA, NOUS UTILISONS DES MODELES DE COUPLAGE QUI EFFECTUENT LA TRANSFORMATION D'UNE TRAJECTOIRE POLYNOMIALE PAR MORCEAUX D'ORDRE N EN UNE SEQUENCE DE TRAJECTOIRES POLYNOMIALES PAR MORCEAUX D'ORDRE M (N ET M ETANT L'ORDRE DES PORTS INTERCONNECTES). CES EXTENSIONS CONTRIBUENT A GENERALISER LE FORMALISME DEVS TOUT EN CONSERVANT TOUS CES AVANTAGES (MODELES HIERARCHIQUES, REUTILISABILITE, RAPIDITE, ETC.). CE MEMOIRE ILLUSTRE CETTE THEORIE AU TRAVERS DE NOMBREUX EXEMPLES, MODELISES ET SIMULES GRACE A UNE PLATEFORME LOGICIELLE DEVELOPPEE A CET EFFET.

This book was released on 1996 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: De nouveaux concepts et techniques de modélisation et de simulation ont été introduits ces dernières années. Une des caractéristiques essentielles de ces concepts, est l'utilisation de formalismes fondés sur des notions mathématiques. En effet, un grand pas a été accompli dans ce sens concernant notamment la modélisation des systèmes à évènements discrets. Cependant, de nombreux systèmes combinent des fonctionnements de types continus, discrets et évènementiels. L'entreprise de modélisation et de simulation de ces systèmes reste difficile du fait de la complexité d'interaction entre les trois modes de fonctionnement. Notre contribution, en l'absence d'un outils de simulation adapte à ce type de systèmes est : 1- de proposer une approche de modélisation dont l'objectif est d'utiliser une structure formelle unique pour la spécification des systèmes dont les états évoluent de façon continue, discrète et sur l'occurrence d'évènements 2- d'implémenter une stratégie de simulation basée sur la théorie des systèmes en utilisant les concepts de l'oriente objet. La stratégie de simulation est conçue de façon à permettre une description modulaire et hiérarchique du modèle. 3- de synchroniser les interactions entre la partie continue et la partie discrète du simulateur en introduisant le concept de temps logique dans les mécanismes de synchronisation par messages.

Available in PDF, EPUB and Kindle. Book excerpt: As a result of its widespread implementation in economic and social structures, the network concept appears to be a paradigm of the contemporary world. The need for various services – transport, energy, consumption of manufacturing goods, provision of care, information and communication, etc. – draws users into interwoven networks which are meshes of material and immaterial flows. In this context, the user is a consumer of goods and services from industries and administrations, or they themselves are part of the organization (digital social networks). This book examines the invariants that unify networks in their diversity, as well as the specificities that differentiate them. It provides a reading grid that distinguishes a generic level where these systems find a common interpretation, and a specific level where appropriate analytical methods are used. Three case studies from different fields are presented to illustrate the purpose of the book in detail.

This book was released on 2018-03-08 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyber-physical systems (CPS) are characterized as a combination of physical (physical plant, process, network) and cyber (software, algorithm, computation) components whose operations are monitored, controlled, coordinated, and integrated by a computing and communicating core. The interaction between both physical and cyber components requires tools allowing analyzing and modeling both the discrete and continuous dynamics. Therefore, many CPS can be modeled as hybrid dynamic systems in order to take into account both discrete and continuous behaviors as well as the interactions between them. Guaranteeing the security and safety of CPS is a challenging task because of the inherent interconnected and heterogeneous combination of behaviors (cyber/physical, discrete/continuous) in these systems. This book presents recent and advanced approaches and tech-niques that address the complex problem of analyzing the diagnosability property of cyber physical systems and ensuring their security and safety against faults and attacks. The CPS are modeled as hybrid dynamic systems using different model-based and data-driven approaches in different application domains (electric transmission networks, wireless communication networks, intrusions in industrial control systems, intrusions in production systems, wind farms etc.). These approaches handle the problem of ensuring the security of CPS in presence of attacks and verifying their diagnosability in presence of different kinds of uncertainty (uncertainty related to the event occurrences, to their order of occurrence, to their value etc.).

Download or read book Modeling Discrete-Event Systems with GPenSIM written by Reggie Davidrajuh and published by Springer. This book was released on 2018-02-28 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling Discrete-Event Systems with GPenSIM describes the design and applications of General Purpose Petri Net Simulator (GPenSIM), which is a software tool for modeling, simulation, and performance analysis of discrete-event systems. The brief explains the principles of modelling discrete-event systems, as well as the design and applications of GPenSIM. It is based on the author’s lectures that were given on “modeling, simulation, and performance analysis of discrete event systems”. The brief uses GPenSIM to enable the efficient modeling of complex and large-scale discrete-event systems. GPenSIM, which is based on MATLAB®, is designed to allow easy integration of Petri net models with a vast number of toolboxes that are available on the MATLAB®. The book offers an approach for developing models that can interact with the external environment; this will help readers to solve problems in industrial diverse fields. These problems include: airport capacity evaluation for aviation authorities; finding bottlenecks in supply chains; scheduling drilling operations in the oil and gas industry; and optimal scheduling of jobs in grid computing. This brief is of interest to researchers working on the modeling, simulation and performance evaluation of discrete-event systems, as it shows them the design and applications of an efficient modeling package. Since the book also explains the basic principles of modeling discrete-event systems in a step-by-step manner, it is also of interest to final-year undergraduate and postgraduate students.

Download or read book Modélisation et simulation des systèmes dynamiques hybrides affines par morceaux written by and published by . This book was released on 2009 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les systèmes hybrides affines par morceaux forment une classe importante et simple de systèmes dynamiques hybrides. Il s'agit d'un ensemble fini de sous-systèmes affines associés à une ou plusieurs lois de commutations qui définissent à chaque instant le système affine actif. Ces systèmes sont non linéaires et peuvent présenter une variété de phénomènes complexes liés à des bifurcations et au chaos. On s'intéresse à plusieurs exemples en électronique de puissance : des convertisseurs de type DC-DC. La modélisation de ces convertisseurs est donnée par des modèles classiques approchés ou discrétisés. Ces circuits peuvent également être analysés en utilisant des modèles hybrides. Le comportement des systèmes hybrides se base sur l'existence d'événements. La simulation qui est un outil simple d'analyse de ces systèmes demande un algorithme qui donne les dates exactes de commutations. Les techniques de détection qui existent se basent essentiellement sur des approximations et elles peuvent omettre certains événements et par suite générer des trajectoires qui divergent radicalement de la trajectoire réelle du système hybride simulé. Notre objectif à travers cette thèse, est de fournir un outil rapide et précis de simulation des systèmes hybrides plans affines par morceaux d'ordre 2. Notre approche semi-analytique utilise l'expression analytique des solutions et donne les instants de commutations des événements d'états et des événements temporels de type périodique. Notre algorithme est implémenté en une boîte à outil sous Scicos et sous Matlab.
