基于最小二乘支持向量机理论,结合某风电场实测风速数据,建立了最小二乘支持向量机风速预测模型。对该风电场的风速进行了提前1h的预测,其预测的平均绝对百分比误差仅为8.55 ,预测效果比较理想。同时将文中的风速预测模型与神经网络理论、支持向量机(support vector machine,SVM)理论建立的风速预测模型进行了比较。仿真结果表明,文中所提模型在预测精度和运算速度上皆优于其他模型。 (Based on least squares support vector machine theory, combined with a wind farm measured wind speed data, the establishment of a wind vector machine forecasting model of least squares support. The velocity of the wind farm were predicted in advance 1h, the mean absolute percentage error of only 8.55 of its forecast, forecast effect is ideal. While the text of the wind speed forecasting models and neural networks, support vector machines (support vector machine, SVM) wind speed prediction models were compared with established theories. Simulation results show that our proposed model on prediction accuracy and computing speed are superior to other models.)

采用遗传算法和例子群算法进行优化，可以采用试验设计方法构建试验样本，用Kriging方法构建适应度函数，然后进行优化求解，记住，采用此程序是，应该安装Kring工具箱子(Using genetic algorithm and example of algorithm optimization, experimental design method can be used to build the test sample, with the Kriging method constructing fitness function, and then optimized solution, remember, is using this program, should be installed Kring tool box)

熟悉信号采样过程，并通过本实验观察欠采样时信号频谱的混迭现象，了解采样前后信号频谱的变化，加深对采样定理的理解，掌握采样频率的确定方法。使用simulink进行仿真。(An example of the signal sampling process. Done with simulink. )
