Beschreibung: Mechatronic systems exhibit an ever increasing level of automation and complexity. A malfunction of such systems may cause significant damage, pollution or danger to humans. Supervision is mandatory in order to maintain safety and reliability, and to fulfill legal requirements. The task of diagnostic algorithms is to detect and isolate faults that may affect the system. Fault detection is concerned with verifying whether or not a system is faulty. Fault isolation tries to find the faulty component in the system.
Mechatronic systems consist of various components, including actuators, sensors, and control units. Due to the size of those systems it is no longer advisable to design diagnostic functions that are based on heuristic analysis or expert knowledge. Instead, systematic methods have to be developed in order
- to analyze whether or not faults are diagnosable, i.e., detectable or isolable, respectively, and
- to build diagnostic algorithms.
The project aim is to provide a comprehensive fault isolation procedure which tackles the two problems.
