摘要
船舶在海上的航行受到海洋气象和水文条件的影响,会产生垂荡、横摇和纵摇等多种形式的运动,这些复杂运动对舰船航行稳定性和船载精密设备的工作精度有不利影响。因此,对船舶的横摇、纵摇等运动进行短时预测具有重要意义。本文系统介绍卡尔曼滤波技术,并利用滤波技术和随机海浪数学模型,研究一种船舶横摇运动的预测方法。
The ship is under the influence of marine meteorological and hydrological conditions at sea, will produce heave, roll and pitch and other forms of exercise, have an adverse effect on the stability of these complex motion of ship and ship precision equipment working accuracy. Therefore, it is of great significance to predict the ship rolling and pitching. In this paper, the Calman filtering technique is introduced systematically, and a new method to predict the ship rolling motion is studied by using the filtering technique and the mathematical model of random wave.
