Abstract

The aim of the project is the modelbased diagnosis of faults in production systems. We use a real-time measurement-system to get the state of the process and to react in a short time to avoid high repair costs. The beha- vior of the process will be simulated with different simulators. The main simulator is a petri-net simulator which calculates the behavior of the en- tire process. The petri-net simulator is a discret simulator and especially in case of discrepancies between the state of the petri-net simulator and the technical process, a continuous simulator is requiered. With this simulator get more information about subprocesses like a pneumatical cylinder. In order to get a high performance diagnosis-system the simulators as well as the diagnosis algorithm are distributed on
