Abstract EN
Using conditional fuzzy clustering, a linguistic model for static pressure signal of compressor outlet in aeroengine was established.
The modeling process and the validation result demonstrated unique advances of linguistic modeling in the analysis of complex systems.
The linguistic model was used to predict the pressure signal before the engine entered instability.
The prediction result showed that the linguistic model could effectively recognize the sudden changes of pressure signal features.
The detected change of signal might not necessarily be the commonly considered initial disturbance of compressor instability; however, the pattern recognition ability of linguistic model was still very attractive.
At last, it pointed out that setting up a database containing experiment data and historical experience about engine aerodynamic instability and utilizing advanced intelligent computing technology in the database to develop knowledge discovery provide a new idea for the solution to the problem of aerodynamic instability in aeroengine.
