Abstract Abstract — This paper presents the implementation of the combination of time-series modeling and nearest neighbor classification method in detecting common faults in rotating machineries. In this paper we propose the utilization of parametric distance as an instrument to diagnose faults. The parametric distance is defined as the Euclidean distance between the vector of parameters of an unknown fault and the vector of parameters of known faults obtained from the learning stage. Since the vectors are defined in a hyperspace spanned by the parameters of the identified time-series model, the parametric distance is definitely metric. The method has been successfully implemented in the laboratory using a simple vibration test rig. Index Terms — Time series modeling, Euclidean distance, fault identification, rotating machinery
