This book was released on 2012 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern control systems in manufacturing are characterized by rising complexity in size and functionality. They are highly decentralized and constitute a network of physically and functionally distributed controllers collaborating to perform the control tasks. That goes along with a further growing demand on safety and reliability. A distributed control architecture supporting functional decomposition of large systems as well as accommodating flexibility of modular systems is defined. This work describes the formal synthesis of distributed control functions for the sub area of safety requirements. The formal synthesis is applied to avoid the potentially faulty influence of human work through the whole process from the formal specification to the executable control function. Starting points are a formal model of the uncontrolled plant behavior and a formal specification of forbidden behavior. The formulation of the specification and the modeling is exemplified on a manufacturing system in lab-scale. The introduced synthesis methods produce controller models describing the correct control actions to achieve the given specification. The methods use symbolic backward search from a forbidden state to determine the last admissible state before entering an uncontrollable trajectory to a forbidden state. Hence, the determination of the reachable state space is avoided to reduce the computational complexity. The use of partial markings leads to a further reduction. The complexity is an important obstacle for the use of formal methods on real-scale applications. The monolithic synthesis approach is proven to result in maximally permissive results. The modular approach is not maximally permissive but the more efficient way to distributed control functions. The implementation of the generated controller model as executable Function Blocks according to IEC61499 is addressed in the last part of this work. The distributed control predicates are embedded as structured text instruction into different interacting Function Block types according to the distributed control structure. This last step finalizes the sequence from a formal model and the specification to fully automatically-generated executable control code.
Book Synopsis Technologies for Engineering Manufacturing Systems Control in Closed Loop by : Sebastian Preuße
Download or read book Technologies for Engineering Manufacturing Systems Control in Closed Loop written by Sebastian Preuße and published by Logos Verlag Berlin GmbH. This book was released on 2013 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diese Arbeit stellt ein Analyserahmenwerk vor, welches zur Uberprufung des korrekten Verhaltens eines technischen Systems eingesetzt wird. Im Fokus steht dabei die praktische Anwendung im industriellen Umfeld. Hierfur werden die verwendeten Formalismen weitestehend durch domanenspezifische Beschreibungsmoglichkeiten substituiert, um somit den Anwender beim Entwurfs- und Analyseprozess zu unterstutzen. Die Arbeit stellt konkrete Techniken vor, um ein formales Anlagenmodell aus bereits vorhandenen Daten zu generieren, um eine formale Spezifikation des Verhaltens des technischen Systems zu erstellen und um das Verhalten des Systems formal zu analysieren. Dabei wird die Steuerungshardware in den Prozess eingebunden und somit die Korrektheit des implementierten Steuerungsprogramms uberpruft. Auf diese Weise lasst sich fehlerhaftes Anlagenverhalten bereits vor der Inbetriebnahme aufdecken und beheben, wodurch die Kosten fur die Fehleranalyse und -korrektur im laufenden Betrieb eingespart werden.

Download or read book Component-Based Software Engineering written by Lars Grunske and published by Springer. This book was released on 2010-06-14 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2010 Symposium on Component-Based Software Engineering (CBSE 2010) was the 13th in a series of successful events that have grown into the main forum for industrial and academic experts to discuss component technology. CBSE is concerned with the development of software-intensive systems from - dependently developed software-building blocks (components), the development of components, and system maintenance and improvement by means of com- nent replacement and customization. The aim of the conference is to promote a science and technology foundation for achieving predictable quality in software systems through the use of software component technology and its associated software engineering practices. In line with a broad interest, CBSE 2010 received 48 submissions. From these submissions, 14 were accepted after a careful peer-review process followed by an online program committee discussion. This resulted in an acceptance rate of 29%. The selected technical papers are published in this volume. For the fourth time, CBSE 2010 was held as part of the conference series: Fed- ated Events on Component-Based Software Engineering and Software Archit- ture (COMPARCH). The federated events were: the 13th International S- posium on Component-Based Software Engineering (CBSE 2010), the 6th - ternational Conference on the Quality of Software Architectures (QoSA 2010), andthe1stInternationalSymposium onArchitecting CriticalSystems(ISARCS 2010). Together with COMPARCH’s Industrial Experience Report Track and the co-located Workshop on Component-Oriented Programming (WCOP 2010), COMPARCH provided a broad spectrum of events related to components and architectures.
