Abstract: The authors develop a controller methodology for fault detection and diagnosis using Petri nets and fault trees in automated manufacturing systems. The controller has two levels. At the first level there are dedicated diagnostic systems for each of the subsystems. At the second level there is an intelligent controller monitoring the part flow and coordinating the local diagnostic systems and controllers. The authors present a Petri-net-based intelligent controller for system-level fault detection and diagnosis.
