A Probabilistic Fault Detection Approach: Application to Bearing Fault Detection
IEEE Transactions on Industrial Electronics, 2011This paper introduces a method to detect a fault associated with critical components/subsystems of an engineered system. It is required, in this case, to detect the fault condition as early as possible, with specified degree of confidence and a prescribed false alarm rate.

The dedicated observer scheme (DOS) for detecting incipient instrument faults by functional redundancy is applied to a simulation of the lateral axis control system of a hydrofoil boat. Observer designs and detection logic are found for which 14 separate instrument faults are detected without false alarms.

Optimal stochastic fault detection filter
Automatica, 2003Any system under automatic control demands a high degree of system reliability. This requires a heat monitoring system capable of detecting any plant, actuator and sensor faults as they occur and identifying the faulty components. In this paper a fault detection and identification algorithm, called optimal stochastic fault detection filter, is ...

A U-shaped tuning fork is fixed to a supporting block connected to a body in which a fault is to be detected. A spring loaded rod is movably supported at one end on the supporting block and extends through a spherical wedge sandwiched between two legs of the tuning fork.

PARAMETRIC IDENTIFICATION FOR ROBUST FAULT DETECTION
IFAC Proceedings Volumes, 2002Abstract The work presents some simulation results concerning the application of robust model–based fault diagnosis to an industrial process by using identification and disturbance de–coupling techniques. The first step of the considered approach identifies several equation error models by means of the input–output data acquired from the monitored ...

Sensors used in the monitoring of machinery with the object of identifying faults are usually related to the dentification of physical and/or chemical changes. As a consequence, sensors are frequently similar to those employed for control purposes and, indeed, there is a considerable similarity between the two techniques.

Principles of model-based fault detection
Annual Review in Automatic Programming, 1992Abstract The paper outlines the principles of fault detection and isolation (FDI) in dynamic systems using a mathematical model of the system. Implemented on a digital computer, these model-based algorithms can efficiently be applied to signal validation, on-line detection of abrupt faults and early fault diagnosis in a long-term system supervision ...
