Fault diagnosis using feature extraction in power plant rotating machinery / Nor Azlan Othman, Nor Salwa Damanhuri and Norhazimi Hamzah.

The aim of this paper is to diagnose the faults that occurred in rotating machinery. Pattern recognition technique was implemented using three main steps of fault diagnosis; feature extraction, dimensionality reduction and fault classification. This paper focuses on the faulty bearing which mainly c...
