HYBRID MODEL BASED DETECTION OF COMPRESSOR STALL

摘要

Systems, tangible non-transitory machine readable computer media, and methods are provided. In one embodiment a system includes an industrial controller having at least one processor configured to: receive a measured input from a turbomachinery having a compressor, execute a hybrid model of the compressor, receive a measured output, compare the measured input to the measured output to derive an error value, perform a signature analysis if the error value is beyond a range; and derive a probability of compressor stall based on the signature analysis.
