Fault Diagnosis on Servo System of Shipborne Satellite Communication Station Based on Expert System
Abstract:Aiming at the problem that fault diagnosis of ship-borne satellite communication station servo system relies on manual experience and is inefficient,a fault diagnosis method based on expert system is proposed. By analyzing the common faults and diagnostic process of servo system,the feature vectors of fault diagnosis are extracted from the system condition monitoring data based on expert experience,and the rules in the knowledge base of expert system are modeled by object-oriented method. Finally,the depth-first algorithm is used to complete fault diagnosis reasoning. Experiments and results show that this method can identify servo system faults quickly and accurately,improve the efficiency of fault diagnosis,and is of great significance to improve the availability and reliability of servo system.
