FIELD: pumps. ^ SUBSTANCE: method and system for detecting the signs of compressor slowing down, stalling and surging, which provide control of, at least, one parameter of compressor, are intended to obtain initial data, reflecting, at least, one parameter of compressor. Initial data are pre-processed by frequency demodulator in order to obtain preliminary processed data subject to further processing using Kalman filter with aim to detect the sighs of slowing-down. ^ EFFECT: increase of pressure in combination with high efficiency. ^ 32 cl 8 dwg |
