论文摘要
通过控制WEC来最大化能量吸收至关重要的，对波能转化器（WEC）的入射波预测至关重要。然而，几乎没有完成对双向波的确定性预测的工作，其组件的波动方向是相反的180 [deg。]。为了分解和预测这种双向波，考虑了三个波浪驾驶浮标的阵列。两侧的浮标都用于将双向波分解为进行性和回归波分量，并且通过这些分解的波浪预测了中浮标的表面升高。确定波的预测基于脉冲响应函数，并提出了余弦过滤的脉冲响应函数，以减少由于函数的无限长度的截断而导致的误差。显示初始均匀双向波的预测证明了脉冲响应函数方法对时间序列预测的性能。进行数值和实验比较以验证我们的建议。
Prediction of incident waves to wave energy converters (WEC) is essential to maximize the energy absorption by controlling the WEC. Nevertheless, little work has been done on the deterministic prediction of bi-directional waves whose wave directions of components are 180 [deg.] opposite. To decompose and predict such bi-directional waves, an array of three wave-rider buoys are considered. Buoys on both sides are used for decomposing bi-directional waves into progressive and regressive wave components, and the surface elevation of the middle buoy is predicted by these decomposed waves. The deterministic wave prediction is based on the impulse response function, and a cosine-filtered impulse response function is proposed to reduce an error due to the truncation of the infinite length of the function. Predictions of initial uniform bi-directional waves are shown to demonstrate the performance of the impulse response function method to time-series prediction. Both numerical and experimental comparisons are carried out to validate our proposals.
