this file represent the model of turbine wind you can use to connect with DFIG machine

任意输入年，月，日，通过输入日期查看它是该年的第几天(Any input year, month, day, it is the first few days)

风险过程概率分布数值算法，金融预测，计算数值的比较 (probability distributions)

时域有限差分法-2维自由空间传输电磁场分布(Finite Difference Beam Propagation Method)

四进制PSK信号的产生，方便大家进行相应信号的的调制实验。(Quaternary PSK signal, facilitate everybody carries on the corresponding signal modulation experiment. )

设计一维纳滤波器 (1)产生三组观测数据：首先根据s(n)=a s(n-1)+w(n)产生信号s(n)，将其加噪（信噪比分别为20dB,10 dB，6 dB），得到观测数据x1(n), x2(n), x31(n). (2)估计xi(n)，i=1,2,3的AR模型参数。假设信号长度为L，AR模型阶数为N，分析实验结果，并讨论改变L,N对实验结果的影响。 (A Wiener filter design (1) to produce three sets of observations: first generating a signal s (n) according to s (n) = as (n-1)+w (n), to add noise (20dB SNR, respectively , 10 dB, 6 dB), to obtain observational data x1 (n), x2 (n), x31 (n). (2) estimate xi (n), i = AR model parameters 1,2,3. Assuming the signal length L, AR model of order N, analysis of experimental results and discuss the impact changing L, N of the experimental results.)

在MATLAB中求图像纹理特征，相控阵天线的方向图（切比雪夫加权），matlab程序运行时导入数据文件作为输入参数，合成孔径雷达（SAR)目标成像仿真，采用加权网络中节点强度和权重都是幂率分布的模型，采用了小波去噪的思想。( In the MATLAB image texture feature, Phased array antenna pattern (Chebyshev weights), Import data files as input parameters matlab program is running, Synthetic Aperture Radar (SAR) imaging simulation target, Using weighted model nodes in the network strength and weight are power law distribution, Using wavelet denoising thought.)

说明：  statcom的simulink实现，采用dq解耦法控制。(STATCOM is built in Simulink, and DQ decoupling method is used to control.)
