Abstract
The present invention relates to an order analysis and diagnosis for a rotor system, characterized in that the system uses Kalman filter or RLS (recursive least square) algorithm for order analysis, and fuzzy theory to determine the failure status. The system comprises: graphical user interface (GUI), developed by LabVIEW and C++Builder, serving as a man machine interface, and integrating the measurement analysis and fuzzy diagnosis; acceleroemeter, using to measure the vibration signals; photo switch, using to record the difference of rotation speed; digital signal processing (DSP) card, using to process the data from the acceleroemeter and photo switch, and calculating the estimate rotational speed; person computer, using to integrate the system.
