Application of Kalman filter on fault diagnosis of hydraumatic motor
Long Chen · Journal of Harbin University of Commerce · 2009
According to the characteristic of hydraumatic motor signal,the principle and recursion algorithm of Kalman filter are introduced and the methods of establishing state and measurement equation based on time series auto recursive model are given out.A way of signal filtering is poroposed according Kalman recursion algorithm and the equations.After system simulation and practical certification,the result shows its affectivity to remove noise from vibration signal by creating the model using AR coefficient coming from Levision-Durbin algorithm.
