Fault diagnosis in hydraulic systems includes a particular difficulty because of the inaccessibility of many hydraulic elements and the possible risk by the searching for possible faults due to the high operating pressures. Knowledge-based methods suitably applied are able to offer effective solutions to the diagnostic problem for these systems. This paper presents the diagnostic difficulties of these systems and the way that knowledge representation structures have been applied to overtake these difficulties. Finally, the paper discusses two methods and their suitability for various requirements of the practice.
