Hydraulic actuator system is one part of turbofan system. The health of this part is of great significance to the operational safety of an aero-engine. Recently with the development of a full authority digital electronic control system (FADEC), the state statistics of fuel control system's core organs have been recorded by the computer, thus provide a basis for a data driven fault diagnosis method. This paper uses simulation software AMEsim to model a hydraulic actuator loop in both normal and abnormal conditions. Then based on a data driven fault diagnosis method-principal component analysis (PCA), a PCA model is built. Finally, using the data obtained from the AMEsim model, the effectiveness of method based on PCA is verified.
