| Abstract: | Targeting on the features of wave compensation stable platform motion response, the articles aims to resolve the unusable displacement integrated in time domain by measuring low frequency response acceleration of the wave compensation stable platform, this method, integrate acceleration in frequency domain based on FFT transform combining with Hilbert transforming, is adopted in this paper. The processed result shows that this method effectively realizes the integration transforming of low frequency acceleration, thus supports the displacement compensation of the stable platform. |
