基于灰色理论的海浪实时预报

在气垫船高速行进过程中,由于其自身的特点,对其运动参数进行精确控制时,需要对海浪进行实时预报,以减小滤波的滞后.文中基于ITTC双参数谱对海浪数据进行了仿真,并将灰色GM(1,1)模型用于海浪信号的实时预报.针对海浪数据的特殊性,提出一种新型的数据预处理方法.预报结果可知,经过镜像数据预处理后,灰色GM(1,1)模型完全可以对海浪数据进行实时预报,其精度满足实际工程需要.

Real-time prediction of ocean waves based on the gray theory

During high-speed movement of hovercraft on the sea,the real-time wave forecast should be ahead taken to minimize the lag of filter for the precise control of the motion parameters due to its self-characteristics.It simulates the ocean-wave data based on ITTC double-parameter spectrums and applies the gray model into the real-time forecast on ocean-wave signals.To the particularity of ocean-wave data,this paper pushes out one new data dispose method.The result proves that the gray model could satisfactorily...
