摘　　要：建立了船低频数学模型，对高频实验数据采用周期图法进行了功率谱估计，并根据功率评估计曲线建立了船高频数学模型。据此设计的有限冲激滤波器和最优估计滤波器已应用在某水面船动力定位系统中，效果良好。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.
