MetadataShow full item record
Methods for avoiding surge in a compressor are provided. A representative method includes detecting precursor information of the compressor and controlling the compressor based on the precursor information to avoid a surge condition in the compressor. The control scheme for the method uses a real time observer for on-line identification of magnitude and frequency of dominant precursor waves. The observer outputs feed into a fuzzy logic control scheme, and the identified frequency and amplitude of the precursors are used to actuate devices, such as a bleed valve and/or a fuel valve, for active control of compressor surge. Systems and other methods are provided.
