1. A method for monitoring a compressor comprising a rotor, the method comprising:
- (a) obtaining a dynamic pressure signal of the rotor;
(b) obtaining a blade passing frequency of the rotor;
(c) using the blade passing frequency signal for filtering the dynamic pressure signal;
(d) buffering the filtered dynamic pressure signal over a moving window time period; and
(e) analyzing the buffered dynamic pressure signal to predict a stall condition of the compressor.
