Multiple regression analysis of bleed valve regulation model based on SVM

Abstract

Abstract: Aero engine's 2.5 bleed valve is an important mechanism to eliminate the risk of stall and surge. Stall and surge mechanism of axial-flow compressor are analyzed; after 30 trouble-free flights'QAR (quick access recorder)data analyzed and disposed, 3 flight sections'identification models of 2.5 bleed valve control models are set up by using SVMmethod. Applicating the models on a flight's QAR data, the bleed valve opening is calculated and compared with the actual value, proving that the models have higher accuracy and certain application value in the condition monitoring and fault diagnosis of aero-engine.

Key words: SVM, regression analysis, identification model, QAR, PW4077D, 2.5 bleed valve
