Abstract
The paper deals with the diagnosis of continuous-variable or hybrid systems whose state can be measured only by means of a quantiser. Hence, the on-line information used in the diagnosis is given by the sequences of input and output events. The paper describes how the quantised system can be represented by a semi-Markov process and how the diagnostic problem can be solved by using this timed discrete-event representation. A specific result is obtained if the model is does not include probabilistic information about the event occurrence. The diagnostic method is illustrated by considering a numerical example which concerns a part of a batch process. The results show that the temporal information included in the semi-Markov process is crucial for fault diagnosis of discrete-event systems.
