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.
