Development of a real-time capable fault detection strategy for pneumatic drives without additional sensors. The core idea is to use limit switches to detect deviations in the extension and retraction time of the pneumatic drive in order to draw conclusions about possible sources of error. For example, a leaking push-in fitting in the piston chamber (leakage (1) in the circuit diagram below) leads to a slower extension movement (delayed pressure build-up) and an accelerated retraction movement (faster venting via the leakage point). By systematically analyzing such effects on the movement time, the Chair of Fluid Mechatronic Systems Engineering has developed a cycle time-based fault detection strategy that can be implemented directly in the machine control system in real time and without additional sensors and test cycles. Following successful laboratory tests, the concept is currently being implemented on industrial partners' demonstrators.

System simulation and selection tools for vacuum systems. Project partner Schmalz has developed a simulation library for vacuum components and various tools for the simulation and selection of support structures and vacuum generators. The selection tools are currently being further optimized and expanded to include AI functions in order to process customer inquiries even faster and more precisely.
