18. A method, comprising:
-
determining a measured surge level based on one or more compressor surge events of an engine system over time; and when a difference between a measured surge level and a modeled surge level is greater than a threshold difference, indicating an external event and updating the modeled surge level with the measured surge level. - View Dependent Claims (19, 20, 21)
