对采集到的振动信号进行EMD分解，得到一系列频率不同的经验模态函数IMF分量，可以用来滤波和提取原信号的特征。(The collected vibration signals of EMD, get a series of different frequency components of IMF empirical mode function can be used to filter and extract features of the original signal.)

说明：  运用Crank-Nicholson差分格式，模拟不同初始风场、垂向涡动系数和风应力拖曳系数下，Ekman风海流随时间的变化情况。(The crank Nicholson difference scheme is used to simulate the change of Ekman wind current with time under different initial wind field, vertical eddy coefficient and wind stress drag coefficient.)

模型预测控制算法是以模型为基础，同时包含有预测的原理；另外，作为一种优化控制算法，它还具有最优控制的基本特征。 (Model predictive control algorithm based on model, and contains prediction of the principle, In addition, as a kind of optimal control algorithm, it also has the optimal control of basic characteristics.)
