Abstract:
It is necessary to compensate for the dynamic measurement‘ s error when using the sensor for dynamic measurement in order to get accurate results. The mathematic model of compensation block can be established by system identification. How ever, the presence of measurement noises could cause certain error in system identification, thus decreasing the accuracy of the measurement. To solve this problem, the output signal of the sensor with additive noises were decomposed, denosied and recon structed by wavelet analysis. The simulation study showed that the approach could minimized the influences of noises.
