This work focuses on the contemporary developments and results in mathematical systems theory and control. The book is written in honour of Diederich Hinrichsen, for his fundamental contributions and achievements in the fields of linear systems theory and control theory, and for his long-term achievements in estabilshing mathematical systems theory in Germany. A key theme of the book is the stability and robustness of linear and nonlinear systems using the concepts of stability radii and spectral value sets. Chapters survey advances in linear and nonlinear systems theory, including parametrizations, problems and behaviours of linear systems, convolutional codes, and complementary and hybrid systems. In addition, the volume examines controllability and stabilization of infinite dimensional systems (allowing for hysteresis nonlinearities) with functional analytic and algebraic approaches.

This volume contains the lectures presented at the workshop on "Advances in Mathematical Systems Theory," held on the island of Borkum, Germany (April 20-23, 1999). The book will be of interest to graduate students and researchers interested in control theory and mathematical systems theory, who will find in-depth analysis and presentations from diverse perspectives interacting in this lively area. The editors are proud to dedicate this volume to Diederich Hinrichsen on the occasion of his 60th birthday in acknowl- edgment of his major contributions to linear systems theory and control theory and his long-term achievements in establishing mathematical sys- tems theory in Germany. We all owe much to him as a teacher, colleague, and friend. The editors thank the Graduiertenkolleg "Komplexe Dynamische Sys- teme" at the University of Bremen as well as the European "Nonlinear Control Network" for providing financial support that enabled this work- shop.Augsburg, Germany Fritz Colonius Wiirzburg, Germany Uwe Helmke Kaiserslautern, Germany Dieter Pratzel-Wolters Bremen, Germany Fabian Wirth Introduction The workshop "Advances in Mathematical Systems Theory" took place in honor of Diederich Hinrichsen on the occasion of his 60th birthday. The following chapters are based on invited lectures and cover a wide range of topics in linear and nonlinear systems theory including parameteriza- tion problems, behaviors of linear systems and convolutional codes, as well as complementarity systems and hybrid systems.

Wie industrielle Problemstellungen zu mathematischen Herausforderungen werden, deren Bewältigung zu überzeugenden industriellen Lösungen führen, wird in diesem Buch ausführlich gezeigt. Neben 6 Fachbeiträgen, in denen exemplarisch bestimmte industrielle Aufgabenstellungen modelliert, simuliert und optimiert werden, zeigen 4 Übersichtsbeiträge, welche Konzepte der Modellierung, Berechnung, Optimierung und Datenanalyse die Arbeit des Fraunhofer-ITWM Instituts bestimmen. Neben einem größeren Abschnitt, in dem die angewandte bzw selbst entwickelte Mathematik detailliert auch für Fachkollegen und Studierende dargestellt wird, enthält jeder Fachbeitrag eine ausführliche Beschreibung der praktischen Aufgabenstellung sowie den Beitrag der erarbeiteten Software zur Bewältigung der industriellen Herausforderungen. Im letzten Kapitel wird gezeigt, wie mathematische Modellierung im Schulunterricht das Bild des Faches verändern und die Freude an der Mathematik verstärken kann.

This book offers an insider's view of how industrial problems are translated into mathematics and how solving the mathematics leads to convincing industrial solutions as well. In 6 technical chapters, a wide range of industrial problems is modeled, simulated, and optimized; 4 others describe the modeling, computing, optimization, and data analysis concepts shaping the work of the Fraunhofer ITWM. Each technical chapter illustrates how the relevant mathematics has been adapted or extended for the specific application and details the underlying practical problem and resulting software. The final chapter shows how the use of mathematical modeling in the classroom can change the image of this subject, making it exciting and fun.
