基于双向差分的船舶横摇时间序列的预报

Time series prediction of ship rolling based on two direction difference

根据船舶在随机海浪作用下的运动特性,基于双向差分算法建立模型,并运用于船舶横摇运动时间序列的预报,取得较好的效果.该模型也可用于纵摇、艏摇的时间序列的预报.

Based on the motion characteristics of ship under ran- dom waves,the model and learning algorithm for two direction difference were given.The experiments of ship roiling time se- ties prediction were done using two direction difference,the re- sult performs well.The method can also be used in ship pitching and heaving time series prediction.
