Structural Fault Detection in Join Free Timed Continuous Petri Nets

:This work is concerned with fault detection in a class of timed continuous Petri nets (TCPN) under Infinite Server Semantics. Faults are deviations from the nominal system behavior due to undesired changes of the transition firing rates or place token losses. These fault types are represented by adding transitions, named fault transitions, to the TCPN model. This work presents a novel characterization of fault detectability in TCPN based on input-output observability results applied to faults. This paper also proposes the design of a diagnoser for detecting fault occurrences in TCPN which is based on a sliding mode observer.
