    摘要: A system for detecting and diagnosing a faultive state of an airplane engine, including: at least one vibration sensor attached to an airplane; a reference model database construction unit; and a fault detection and diagnosis unit which estimates a parameter of a model, obtains a test variable and a numerator coefficient value difference of a transfer function between the models, and the covariance of parameter estimation error, and diagnoses the faultive state and the faultive cause of the airplane engine. Accordingly, the present invention can determine the faultive state and the detective cause of the airplane engine using the vibration data of the airplane engine.
