Systems and methods for controlling an industrial asset of an asset family

A system for controlling an industrial asset of an asset family, wherein the asset family comprises a plurality of industrial assets, the system comprising:

• at least one sensor operably coupled to the industrial asset;
• and
• a controller communicatively coupled to the at least one sensor, the controller comprising at least one processor configured to perform a plurality of operations, the plurality of operations comprising:
• determining a plurality of frequency-parameter pairings corresponding to at least one power spectral density of the industrial asset, each frequency-parameter pairing comprising an energy-level distribution for a parameter of the industrial asset across a plurality of frequency intervals of a portion of the at least one power spectral density,
• determining a deviation score for each of the plurality of frequency-parameter pairings, wherein each of the deviation scores is indicative of a magnitude difference between the energy-level distribution of each frequency-parameter pairing and a corresponding energy-level distribution of a nominal frequency-parameter pairing of the asset family,
• determining a multi-variate anomaly score based, at least in part, on the deviation scores,
• determining a fault probability for the industrial asset based, at least in part, on the multi-variate anomaly score, and
• implementing a control action based on the fault probability exceeding a fault threshold.
