摘要
舰船运动姿态预报可更好地保障舰船各项作业的顺利进行,提高航行安全性。该文从频域角度仿真随机风浪,据此仿真舰船运动。考虑到舰船运动姿态时域上的非线性、非平稳特点,采用多层AR模型进行舰船运动姿态预报,并根据仿真案例进行预报检验。多层AR方法能有效提高极短期预报的精度。
Prediction of ship movement can guarantee the operations carried on more smoothly, and improve the safety of ship navigation. This paper simulates the ship movement based on random wave＇s simulation in frequency domain. A method multi-layer autoregressive is used to predict the ship motion with a view to tile nonlinear and non-stationary trait in time domain, and the method is verified with the simulation cases. The result indicates that the Multi-layer AR method can improve the forecast accuracy in extreme short term prediction.
