Aiming at higher reliability requirement for sensor fault detection for air conditioning system of satellite fairing,on the basis of analysis on common fault modes,which focuses on improving the performances of traditional detection methods based on data-driven,adopt a fault detection method based on statistics kernel principal component analysis( SKPCA ),sensor fault detection model based on SKPCA is established,in addition,make validation experiment for common bias faults. Correctness and effectiveness of SKPCA on fault detection is verified by results of experiment.
