As modern control systems become more and more complex and control algorithms more and more sophisticated, the issues of cost efficiency, reliability, availability, operating safety are of major importance. Since no system in practice can work perfectly all the time under various environmental changes and conditions, it is vital to be able to detect and identify the possible faults and failures in the system as early as possible, so that necessary measures can be taken to prevent significant performance degradation, damages to equipment or even lives of staff.
