OFB search algorithm (PSIgram)

Bearing fault feature extraction approach

This code represents a method for fault feature extraction of rolling element bearing based on an optimal frequency band search approach. Although this method is only a specific fault feature extraction method for bearing, the two key technologies, namely FBOSFB and PSI, can be regarded as a versatile feature extraction tool suitable for a wide range of application scenarios, including intelligent fault identification, classification, and residual useful life prediction in rotating machinery.
