PMSG网侧的结构包括逆变器、PWM发生器、电压矢量控制。采用电压外环和电流内环的双闭环控制。设计电流控制器时，希望稳态电流无静差，而且动态要求上，永磁直驱风力发电系统中不允许在电流调节过程中有太大的电流超调.(PMSG network side structure includes an inverter, PWM generators, voltage vector control. Using a voltage outer and inner current double closed loop control. Design current controller, hope no static error steady-state current, and the dynamic requirements, permanent magnet direct drive wind power system does not allow much of the current overshoot in the current regulation process.)

无标度网络结构相对简单,实现算法与可视化并不困难。与其它语言相比,Matlab 语言具有丰富的数学 函数库,能够写出简约的源代码。对于非计算机专业的大学生来说,以此为基础,能够快速进入复杂网络前沿 研究课题,对其数学建模能力和科研能力的培养极为有益。(Scale-free network structure is relatively simple algorithm is not difficult and visualization. Compared with other languages, Matlab language with a rich library of mathematical functions, can be simple to write the source code. For non-computer science students is as a basis to quickly enter the complex network of cutting-edge research topics, their mathematical modeling and scientific research is extremely useful ability.)

The following attachment contains codes in Matlab for digital signal processing. In the file code is for digital signal convolution

说明：  继续上传我自己遍的信道！谢谢！ 这个我没有完全的调试成功，请指正！(to upload my own times of the Road! Thank you! This I did not successfully complete debugging, Hi!)

EM算法计算混合高斯模型，可以计算三个参数。(Gaussian mixture model EM algorithm, three parameters can be calculated.)

胞参考映射点映射法，完整的胞映射程序。已经使用duffing验证。(Mapping cell reference point mapping method, a complete cell mapping program. Have used duffing verification.)

MATLAB源程序，可以利用该程序直接进行线性滤波法模拟风速谱及功率谱(MATLAB source, you can use the program directly to the linear filtering method to simulate the wind speed spectrum and power spectrum)
