摘要
针对船舶纵摇运动系统的灰色特性,利用拓扑预测法与GM(1,1)模型,研究船舶在海浪中非线性纵摇运动的预报问题,分别建立船舶纵摇运动的拓扑预测模型和船舶纵摇运动的GM(1,1)模型。根据实测船舶纵摇运动数据的特点,探讨拓扑预报模型的阈值选取方法。仿真结果表明:采用拓扑预测模型对船舶纵摇运动预报研究是合理且可行的。
Aimed at the grey characteristic of ship pitch motion system, the topology forecasting model and GM（1,1） model are applied to investigating the prediction problems in the nonlinear ship pitch motion in waves. Based on that, a topology forecasting model and GM （1, 1） model of ship pitch motion are constructed respectively. According to the characteristics of the ship pitch motion data obtained from the laboratory experiment, a method of threshold selection is explored for the topology forecasting model. Simulations illustrate that the prediction of ship pitch motion is reasonable and feasible based on this topology forecast model.
