The paper concerns the problem of fault diagnosis of discrete-event systems which are represented by automata. According to the principle of consistency-based diagnosis, methods for detecting and identifying faults in a dynamical system are based on the investigation whether the measured sequences of input and output symbols are consistent with the model of the faultless or the faulty system. As usually no a-priori information about the initial state of the system is available, the diagnostic algorithm has to solve a state observation problem, which will be described at the beginning of the presentation.The basic idea of this method is then used for diagnostic purposes and later generalised to nondeterministic, stochastic and timed automata. Applications to industrial processes illustrate the effectiveness of the method.
Jan Lunze obtained the diploma
in Technical Cybernetics, the PhD, and the DrSc. degrees
(Habilitation) all from the Technical University Ilmenau (Germany).
Between 1992 and 2001 he was Professor of Control Engineering at the
Technical University Hamburg-Harburg. Now he is Professor of Automatic
Control and head of the Institute of Automation and Computer
Control at the Ruhr-University Bochum where he teaches system and
Professor Lunze's research interests are in control theory,
particularly in the field of networked control systems, where he coordinates
the Priority Programme on Control Theory of Digitally Networked Systems,
in hybrid dynamical systems, in discrete-event systems and in applications
of knowledge processing to dynamical systems. He is author
and co-author of numerous research papers and has written several books
including "Regelungstechnik" (Springer, several editions since 1996), "Ereignisdiskrete
Systeme" (Oldenbourg 2006) and co-authored "Diagnosis and Fault-Tolerant Control"
(Springer 2003, 2006).
