基于快速傅里叶变换的谐波叠加法风速时程模拟，虽然是已有算法，但是经过自己切实操作保证可用，并且加入频谱比较以及结果输出-Fast Fourier Transform harmony superposition method simulation process when wind speed, although the existing algorithms, but through their own operations to ensure the effective available, and adding the results and compare the spectral output
