Powerful and elegantly simple.
The field of "On-Line Fault Detection and Supervision in the Chemical Process Industries" is relatively young. Major activity in this area has taken place only in the last fifteen years. The goals of the first workshop in Delaware were to discuss various methodologies necessary for solving industrial problems in fault diagnosis/supervision and to encourage interactions between academia and industry. This workshop also focused on development and evaluation of methodologies for on-line fault detection and supervision in the chemical process industries. It addressed theory, application, validation, performance and evaluation of methodologies such as parameter estimation, observers, parity equations, signal analysis methods, classification, rule-based systems with probabilistic approaches, fuzzy logic and neural networks. There are several trends that make the topic of this workshop especially relevant in today's world. The first is the tremendous advances made in automation and information technology that can potentially bring in an ever-increasing amount of information on to computer screens in the operating room of a plant. Avoiding problems of information overload and converting plant data to "on-line useful knowledge" is a key challenge. In some respects, one can draw parallels here to biological evolution where, over billions of years, human beings have evolved "mental models" to interpret the huge amount of information received through their senses. In the absence of the time advantage that evolution has had, we have to rely on methodologies such as those presented in this workshop to provide assistance to operators and engineers in interpreting plant information. A second trend that makes this field relevant in today's world is the increasing emphasis on environment and safety. Community activism and accidents such as those in Bhopal, India have caused media spotlights to be turned on the smallest of toxic releases or loss of life due to chemical accidents. The negative publicity generated by such events as well as the need to maintain the image of an environmentally conscious company make industry more sensitive to the issues of early detection of faults. The third trend that makes this field very relevant is that of
the globalization of the world economy. Increasing globalization of
the chemical process industry puts pressure on economic
competitiveness and higher productivity. This implies reduced
down-time due to faults, quick and flexible response of production
to supply and demand changes, increasing reliance on automation and
reduced personnel.
It is increasingly accepted that future dependable, real-time
digital computer control systems will have distributed
architectures. Advantages of distributed computer control systems
include the possibility of composing large systems out of
pre-tested components with minimal integration effort, their
well-defined fault containment properties and their capacity to
make effective use of mass-produced silicon chips. The IFAC Workshop series on Distributed Computer Control Systems
(DCCS) focuses on design requirements and fundamental principles
encountered in such systems and highlights and traces the growth of
key concepts at their various stages of development. Theoretical
and application-oriented viewpoints receive equal emphasis. These
Workshops also provide an excellent forum for the exchange of
information on recent technological advances and practices in the
distributed computer control field. The 1997 DCCS Workshop was notable for the attention given to
practical implementations of ideas that have been under discussion
for decades and maintained the high technical standard set by
previous Workshops in the series - the policy of concentrating on a
specific topic, inviting a number of key authors and of accepting
only a limited number of papers paid dividends.
This volume contains the proceedings of the IFAC Workshop on "Singular Solutions and Perturbations in Control Systems "(SSPCS-97) held at Pereslavl-Zalessky, Russia on 7-11 July 1997. The Workshop was sponsored by IFAC and organized jointly by the Russian National Committee of Automatic Control, the Program Systems Institute and the Institute for Information Transmission Problems at the Russian Academy of Sciences, and the University of Pereslavl. The objective of this workshop was to provide an international forum for the discussion of recent developments and advances in the fields of singular control problems, impulsive control, singular perturbations technique in control systems, computational problems and others. The Workshop was devoted both to theoretical and applicative aspects of the so-called "nonclassical" problems in the area of control theory, such as problems with singular perturbations, impulse and generalized controls. These problems arise in various areas of applications, including mechanics, information processing, medicine and economy. At the same time they stimulate the development of new mathematical tools in the classical theory of control and differential equations. All papers included in this volume are given in the form presented by the authors.
Control often follows predictions: predictive control has been highly successful in producing robust and practical solutions in many real-life, real-time applications. Adaptive prediction covers a variety of ways of adding 'intelligence' to predictive control techniques. Many different groups, with widely varying disciplinary backgrounds and approaches, are tackling the same problem from different angles; these groups are sometimes unaware of alternative approaches from other disciplines. This book attempts to give a unified and comprehensive coverage of the principles and methods that these groups have developed. It avoids basing its descriptions on very complex mathematical formulations but still gives a rigorous exposure to the subject, and illustrates the theory with many practical examples. It is chiefly aimed at students, researchers and practitioners, but will also be accessible to the non-specialist.
On-line and off-line quality control are the two methods used to
discern a products reliability of quality. Though they are
disparate techniques, both methods are used to achieve the same
result. This introductory textbook integrates the two techniques to
present a wide coverage of statistical methods of quality control.
The text is compact, stressing the key ideas and concepts rather
than trying to cover each method in complete depth. Statistical
Aspects of Quality Control is an excellent starting point for a
student interested in learning more about the field of statistical
quality control. References and suggested readings are included at
the end of each chapter.
Praise for the Series:
The term ""Taguchi methods"" was coined in the United States. It pertains to the evaluation and improvement of the robustness of products - or what may also be termed ""quality engineering"". The purpose of this book is to explain these terms and it is aimed at managers, technology developers and engineers of manufacturing enterprises. The book contains a general discussion about the productivity of manufacturing enterprises, which is equivalent to cost reduction and quality improvement at the following five manufacturing stages - technology development, product planning, product design, design of the production process and management of the production process.
Philipp Wittke charakterisiert spanlos gefertigte Innengewinde aus den Aluminium- und Magnesiumlegierungen AlSi10Mg, AZ31 und AZ91. Neben der Entwicklung einer zerstoerungsfreien Methode zur Beurteilung der Gewindequalitat werden vom Autor grundlagenorientierte Untersuchungen durchgefuhrt, um den Einfluss von Prozessparametervariationen wahrend der Gewindefertigung auf die Mikrostrukturen und somit auf die quasistatischen und zyklischen Eigenschaften der Innengewinde zu ermitteln. In diesem Zuge werden Strategien zur Abkurzung der Versuchszeiten fur zyklische Untersuchungen entwickelt, bei denen mittels anwendungsoptimierter Sensorik charakteristische Kennwerte zur Lebensdauervorhersage ermittelt werden. Der Autor: Philipp Wittke arbeitete als wissenschaftlich Beschaftigter am Fachgebiet Werkstoffpruftechnik (WPT) der Technischen Universitat Dortmund und schloss dort seine Promotion mit dem Fokus auf die zeiteffiziente Charakterisierung der Ermudungseigenschaften neuartiger Gewindeverbindungen in Kooperation mit dem Institut fur Spanende Fertigung (ISF) der Technischen Universitat Dortmund ab.

Der Autor stellt den Aufbau- und die Wirkungsweise der unterschiedlichen Ausrustungsstufen dar und beschreibt die einzelnen Komponenten der Fahrzeug- und Streckeneinrichtung. Mit den von ETCS unterstutzten Betriebsarten wird aufgezeigt, wie ETCS in den verschiedenen Landern in den Bahnbetrieb integriert werden kann. Durch die Darstellung grundlegender technischer Zusammenhange und Sicherungsfunktionen wird ein Verstandnis fur das zukunftige einheitliche Europaische Zugsteuerungs- und Zugsicherungssystem geschaffen.
Innerstadtische Schienenverkehrssysteme stossen bei steigender Verkehrsnachfrage zunehmend an ihre Grenzen. Die Sicherheit und die Leistungsfahigkeit dieser Verkehrssysteme werden wesentlich durch die eingesetzte Leit- und Sicherungstechnik bestimmt. Eine Ausweitung des Verkehrsangebots erfordert leistungsfahige signaltechnische Systeme, die als Communications-Based Train Control (CBTC) bezeichnet werden. Lars Schnieder stellt in diesem essential die Systemumgebung dar, in die sich die CBTC-Systeme in Nahverkehrsunternehmen integrieren. Daruber hinaus leitet er her, welchen Beitrag die einzelnen Sicherungsfunktionen von CBTC-Loesungen zur Gefahrdungsbeherrschung leisten. Auf dieser Grundlage zeigt der Autor, wie mit zunehmender Automatisierung sukzessive ein hoeherer Funktionsumfang von technischen Systemen ubernommen wird. Zum Abschluss diskutiert er an CBTC-Systeme gestellte nicht-funktionale Anforderungen wie Sicherheit, Verfugbarkeit, Leistungsfahigkeit und Wirtschaftlichkeit. Der Autor: Dr.-Ing. Lars Schnieder verantwortet in einer Software-Entwicklungsfirma das Geschaftsfeld Sicherheitsbegutachtung. Er ist international als anerkannter Sachverstandiger fur Zugsicherungsanlagen tatig.
