Abstract

Diagnosis and prognosis has become essential functions for many safety critical systems in commercial, industrial, and military applications to improve the system availability, survivability, and safety. The challenge of diagnosis is to detect a fault as early and accurate as possible in the operation a system. Early and accurate detection provides a good initial condition for prognosis and allows more time to remedial and correction measurement to avoid operations that can endanger the system safety. After a fault is detected, prognostic algorithms project the current fault state into the future and predict the time to failure or remaining useful life. This presentation explores some of the most important aspects associated with the problem of fault diagnosis and prognosis and presents some application examples in a particle filtering based framework to illustrate the development and deployment of fault diagnosis and prognosis to engineering systems.
