Rotor-System Log-Decrement Identification Using Short-Time Fourier-Transform Filter

With the increase of the centrifugal compressor capability, such as large scale LNG and CO2 reinjection, the stability margin evaluation is crucial to assure the compressor work in the designed operating conditions in field. Improving the precision of parameter identification of stability is essenti...
