Considering the problem of fault diagnosis for sensors and gas-path component in aero-engine, the calculation method of Deng's grey analysis is introduced to design sensors and components fault detection and isolation system. The typical engine failure mode data of the normal condition is obtained by interpolation in the system. Establish the failure standard sequence which is used to grey analysis...
The azimuth and elevation variation rules of a short-range, low-flying target is firstly analyzed in this paper, then the target air route is predicted using a weighted least squares parabolic regression parameter estimation method - firstly the input signal is filtered, then one step prediction is carried out. This method has advantages of easier formula derivation and less intermediate variables...
