Book Identification and Fault Diagnosis of Industrial Closed loop Discrete Event Systems

Download or read book Identification and Fault Diagnosis of Industrial Closed loop Discrete Event Systems written by Matthias Roth and published by Logos Verlag Berlin GmbH. This book was released on 2010 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Die Wettbewerbsfahigkeit von Industrieunternehmen hangt massgeblich von der Produktivitat der eingesetzten Anlagen und Produktionsprozesse ab. Um ein hohes Mass an Produktivitat zu garantieren, mussen durch Fehler verursachte Standzeiten so kurz wir moglich gehalten werden. Dazu werden effiziente Methoden zur Fehlerdiagnose benotigt. In der vorliegenden Arbeit wurde ein modellbasiertes Diagnose-Verfahren fur ereignisdiskrete Closed-Loop Systeme entwickelt. Die betrachteten Systeme bestehen aus dem geschlossenen Kreis von Steuerung und Prozess. Durch den systematischen Vergleich von aktuell beobachtetem und durch ein Systemmodell erwartetem Verhalten konnen Fehler in Echtzeit erkannt und isoliert werden. In der Arbeit wurden geeignete Modellidentifikationsverfahren fur Ereignisdiskrete Systeme entwickelt, sodass die aufwandige manuelle Modellbildung vermieden wird. Die entwickelten Methoden wurden im Labor und im Rahmen einer Industrieanwendung erfolgreich getestet.

Book Discrete Event Systems in Dioid Algebra and Conventional Algebra

Download or read book Discrete Event Systems in Dioid Algebra and Conventional Algebra written by Philippe Declerck and published by John Wiley & Sons. This book was released on 2013-02-13 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book concerns the use of dioid algebra as (max, +) algebra to treat the synchronization of tasks expressed by the maximum of the ends of the tasks conditioning the beginning of another task – a criterion of linear programming. A classical example is the departure time of a train which should wait for the arrival of other trains in order to allow for the changeover of passengers. The content focuses on the modeling of a class of dynamic systems usually called “discrete event systems” where the timing of the events is crucial. Events are viewed as sudden changes in a process which is, essentially, a man-made system, such as automated manufacturing lines or transportation systems. Its main advantage is its formalism which allows us to clearly describe complex notions and the possibilities to transpose theoretical results between dioids and practical applications.

Book Contributions    la synth  se de commande des syst  mes      v  nements discrets

Download or read book Contributions la synth se de commande des syst mes v nements discrets written by Maen Atli and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Un Système de production peut être représenté par les systèmes à événements discrets. En dehors de la planification (où les gens travaillent avec des ratios de produits fabriqués par semaine ou par jour), la modélisation pourrait être basée sur les concepts d'événement et d'activités. Un événement correspond à un changement d'état. Une activité est une boîte noire d'encapsulation de ce qui se passe entre deux événements. En utilisant les réseaux de Petri (RdP), les événements sont représentés par les transitions, et les activités par les lieux. Notre travail propose une synthèse de commande par supervision pour les systèmes d'événements discrets modélisés par une classe de réseaux de Petri appelé graphe d'événements. L'objective de cette thèse est de concevoir un superviseur capable d'aider à améliorer la performance de système et de protéger le système en respectant des spécifications données par le fabricant ou le client selon les besoins et les conditions de travail. Pour modéliser ces spécifications, nous avons proposé un nouveau modèle mathématique de contrainte, appelé Contrainte d'Exclusion de Marquage (CEM). La deuxième contribution principale de ma thèse est de synthétiser une technique efficace et simple pour construire un superviseur qui impose le système de respecter des contraintes en évitant l'ensemble des états interdits modélisé par CEM. Nous avons également développé cette synthèse pour résoudre le problème d'existence des événements incontrôlables et des événements inobservables. Parfois, afin d'étudier les aspects liés à la performance, nous devons prendre le temps en considération. Donc, nous avons résolu aussi le problème des événements temporisé en utilisant RdP temporisés soumis à CEM.

Book Identification des syst  mes      v  nements discrets par r  seaux de Petri

Download or read book Identification des syst mes v nements discrets par r seaux de Petri written by Rebiha Berghoute Bekrar and published by . This book was released on 2009 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans ce travail, nous proposons deux méthodes originales d'identification d'une classe de systèmes à événements discrets (SED) modélisables par réseaux de Petri (RdP). La première méthode consiste à utiliser les signaux de sortie du système afin d'élaborer son modèle comportemental sous la forme d'un RdP. Les conditions nécessaires et suffisantes pour garantir l'unicité de la solution sont établies. Par ailleurs, le problème d'identification d'un SED est défini sous la forme d'un problème de programmation linéaire binaire. Quant à la deuxième méthode, elle est basée sur l'analyse des signaux d'entrée et de sortie mesurables du système considéré. Elle consiste à déterminer la partie mesurable et à estimer la partie non mesurable puis, à calculer la structure et le marquage initial du RdP à identifier. Par ailleurs, deux approches de synthèse de contrôleur RdP sont proposées. Ces derniers permettent de raffiner les modèles issus de la première phase en inhibant, quand c’est nécessaire, l’atteignabilité des états interdit. Les résultats obtenus dans ce travail ont été validés sur un système réel

Book Synthesis and Control of Discrete Event Systems

Download or read book Synthesis and Control of Discrete Event Systems written by Benoît Caillaud and published by Springer Science & Business Media. This book was released on 2002-01-31 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first motivation of Synthesis and Control of Discrete Event Systems is to inform the reader of recent developments and current trends in system synthesis. This is a field of active research aiming to supply efficient techniques for developing safe systems in various areas, covering control of embedded and manufacturing systems, distributed implementation of systems and protocols, and hardware circuits. In all areas, considerations about distribution and care for an efficient implementation of the synthesised systems play an increasing role, justified by better applicability to problems encountered in the design of practical systems. The second motivation of the book, which is a selection of presentations given at two workshops on synthesis of controllers and on synthesis of concurrent systems, is to incite the research community to establish stronger links between two subjects that could be better related, as several presentations do show. The selected papers are research papers ranging from theory to practice, with automata, products of automata and Petri nets playing a prominent role. All areas mentioned above as areas of application of system synthesis are covered by some of the selected papers.
