Abstract

An apparatus for diagnosing and controlling the aerodynamic stability of a compressor and method there of are provided. The apparatus includes a measurement device (), a signal processing device () and a control and execution device (), wherein the measurement device () is configured to measure the pressure or velocity fluctuations of air flows in different positions inside a compressor in real time, and to transmit real-time measurement signals obtained from different positions to the signal processing device (); the signal processing device () is configured to determine, according to the real-time measurement signals, a type and spatial distribution of instability precursor in the compressor, and to output corresponding control strategy signals to the control and execution device (); and the control and execution device () executes, according to the received control strategy signals, corresponding control actions to regulate the stability of the compressor (S).
