Model Adjustment and Multi-Model Based Fault Diagnosis for Hydraulic Servo Axis
This paper presents a model adjustment and a multi-model based fault diagnosis approach. Both methods are based on the same idea. A physical model of the process is altered such that it mimics the behavior of the process in the presence of certain faults. A number of these modified models, each governing a different fault condition, are evaluated and the model with the smallest output error is ...
متن کاملMulti-Model Based Fault Detection and Diagnosis of a Hydraulic Servo Axis
Abstract: This contribution describes the design and implementation of a multi-model based fault detection and diagnosis system for a hydraulic servo axis. Multiple models are operated in parallel to the plant similar to a bank of observers. Beside one model mimicking the fault free process, there are additional models describing the process behavior in the presence of both actuator and process...
متن کاملA Fuzzy Rule Based System for Fault Diagnosis, Using Oil Analysis Results
Condition Monitoring, Oil Analysis, Wear Behavior, Fuzzy Rule Based System Maintenance , as a support function, plays an important role in manufacturing companies and operational organizations. In this paper, fuzzy rules used to interpret linguistic variables for determination of priorities. Using this approach, such verbal expressions, which cannot be explicitly analyzed or statistic...
متن کاملStudy on Knowledge -based Intelligent Fault Diagnosis of Hydraulic System
A general framework of hydraulic fault diagnosis system was studied. It consisted of equipment knowledge bases, real-time databases, fusion reasoning module, knowledge acquisition module and so on. A tree-structure model of fault knowledge was established. Fault nodes knowledge was encapsulated by object-oriented technique. Complete knowledge bases were made including fault bases and diagnosis ...
متن کاملDisplacement Sensor Fault Tolerance for Hydraulic Servo Axis
In this paper, a fault management system for a hydraulic servo axis is described. This system is capable of sustaining faults in the piston displacement sensor of the position-controlled hydraulic servo axis. By means of a parity equation based fault detection stage, faults in the displacement sensor as well as other sensors and components of the servo axis can be detected and subsequently be d...
