Abstract: A non-transitory computer-readable storage medium storing one or more processor-executable instructions wherein the one or more instructions, when executed by a processor of a controller, cause acts to be performed including receiving signals representative of pressure between respective compressor blade tips and a casing of a compressor at one or more stages, generating multiple patterns based on a permutation entropy window and the signals, identifying multiple pattern categories in the multiple patterns, determining a permutation entropy based on the multiple patterns and the multiple pattern categories, predicting an anomaly in the compressor based on the permutation entropy, comparing the multiple pattern categories to determined permutations of pattern categories when an anomaly is present in the compressor, and predicting a category of the anomaly based on the comparison of the multiple pattern categories to the determined permutation of pattern categories.

Abstract: Various methods and systems are provided for detecting a change in turbocharger performance. In one example, a method comprises determining a level of turbocharger imbalance based on output from a turbine speed sensor and generating a signal related to a change in a performance level of the turbocharger if the level of turbocharger imbalance is greater than a threshold.
