| Abstract: | A low-frequency mathmatic models for marine use is build and presented in this paper. For high frnequency experimental data, periodgram method is used to estimate power spectrum, according to the power spectrum, marine high frequency mathmatic model is established. Finally, two filters designed according to this method have been applied in some surface vessel's dynamic positioning system and good simulation results are obtained. |
