Rotating machinery's faults such as unbalanced mass, eccentricity, and bearing fracture make the characteristic features of vibration different from that of normal operating condition. Fault diagnosis of the rotating machinery is achieved by the following ways: Firstly, identify the system in normal condition with a linear model. Secondly, assess the stochastic characteristic of the system in order to define the threshold of abnormal condition and to design a digital filter appropriate for the system. Finally, diagnose the system fault by error difference evaluation and by STFT analysis. The developed algorithm is experimentally verified for a CD-ROM drive.
