Abstract

In order to exploit the inherent redundancy in the displacement transducer and accelerometer information

the collocated displacement and acceleration measurements are integrated

which may improve the accuracy of the vibration test data.An multi-rate Kalman filtering data fusion method for displacement and acceleration measurements based on Wiener process acceleration model is investigated.At the beginning

the multi-rate Kaman filtering data fusion model is introduced

then the optimal estimation for the displacement

velocity as well as acceleration are obtained based on the displacement and acceleration measurements.In addition

Kalman filtering smoothing step could yield the improved estimation accuracy.In the end

the effects of noise level and sampling rate ratio are investigated with comparison to the reference 1

which shows the effectiveness and noise robustness of the method.
