Application of Wavelet Analysis on Gyro Signal Detecting
Hao Yang · Ordnance Industry Automation · 2007
Based on the model of gyro excursion signal,Wavelet Analysis simulation and investigation are taken on the signal that contains the first kind mutation points.Suppose the system went wrong(system frequency saltated at 100s and then recovered at 200s),the Wavelet function of signal processing is Daubechies Wavelet.Before using the db6 Wavelet for three-layer analysis on the signal,the Wavelet Analysis technique was also used for eliminating noise.Through experiment analysis,Wavelet Analysis technique can instantly test out the location and time that Gyro fault take place,so Gyro reliability could be greatly improved.
