Systems And Methods For Improved Anomaly Detection For Rotating Machines

Abstract: The present disclosure relates to systems and methods for improved anomaly detection for rotating machines. An example method may include determining a rotational speed of a rotating machine. The example method may also include determining, using a frequency domain transform of a signal of the rotating machine, a frequency domain signal. The example method may also include determining, based on the rotational speed of the rotating machine, a first frequency band within the frequency domain signal for identifying a fault frequency of the rotating machine. The example method may also include determining a fault frequency of the rotational machine within the first frequency band. The example method may also include determining, based on the fault frequency, a second frequency band within the first frequency band, wherein the second frequency band includes the fault frequency. The example method may also include determining, based on the second frequency band, a first fault index and a baseline of the first fault index. The example method may also include determining, based on a deviation of a second fault index from the baseline, a fault condition of the rotating machine. The example method may also include providing an alert based on the fault condition of the rotating machine.
