Research on Fault Isolation of Ship Rudder Electro-Hydraulic Servo System
In order to further explore how to improve the operation quality of the ship's rudder electro-hydraulic servo system,the article starts from the perspective of fault diagnosis,and explores how to isolate the faults of the common valve-controlled ship's rudder electro-hydraulic servo system,in order to improve the effect of fault diagnosis.Based on the practical needs,this study successfully establishes a multi-observation model synchronous collaboration fault isolation method after modelling analysis.From the simulation test results,each observation model shows better performance in fault isolation,which proves the theoretical feasibility of the fault isolation method,and it is expected that the method will have potential practical application value in the subsequent work.
