dynamic and steady state modeling of Doubly fed induction generator back to back supply in wind power system using MATLAB

用matlab编程和数值计算的书籍，里面有许多源代码。(And numerical calculation using matlab programming books, there are many source code.)

ImageM integrates into a GUI several algorithms for interactve image processing and analysis. It allows to load images, apply filtering and/or segmentation, and run basic analyses. Interface is inspired the open source software ImageJ . To install, simply unzip, and add the path containing the +imagem directory. The application can be launched by typing: ImageM( rice.png ) (or any other image provided with the image processing toolbox). The development of ImageM started as a proof of concept for creating GUI dedicated to image processing. After adding several tools and options, I thought it could be useful to others, and maybe be used as an example of gui development. ImageM relies on the image processing toolbox and on the GUI Layout Toolbox. Most algorithms are wrapped into a specific Image class that allow to process in a unified way grayscale, binary and color images, 2D or 3D, and that can be used independently.

中值滤波 原图像画面清晰，添加了椒盐噪声以后图像上出现了明显噪声，经不同模板的中值滤波处理后图像上的噪声被虑去，但使得图像变得模糊，并且，使用的模板越大，去噪声效果越好，同时图像也越模糊。滤波效果明显优于平滑滤波。 (Median filtering the original image, a clear picture of the Salt and pepper noise added after the image there is a clear noise, and by different template after median filtering has been taking into account the noise on the image to go, but makes the image become blurred, and, using the template more large, to noise, the better the effect, while the more blurred the image. Filtering effect is superior to smoothing.)

用双线性变换法设计IIR数字滤波器 滤波就是将外界干扰的不需要的频率滤除掉，一面影响要测试数据的结果。比如如果是心电波的话，如果这是外界有很大的噪声干扰，滤波就是把不必要的信号给抑制掉，以便对心跳的正常测试。通过图比较，滤波后的明显比之前的要平滑，就是滤去干扰噪声的结果。采样间隔对实验有影响，取的过大会导致频率混叠。(Bilinear transformation method using digital filter IIR filter design is to outside interference filter out unwanted frequencies, while the impact to test data results. For example, if it is so heart waves, if this is a great noise outside interference, filtering is unnecessary signal out to the curb in order to test the normal heartbeat. Through chart comparison, after filtering than before to smooth the noise interference is the result of least squares. Sampling interval of the experiment affect take-off frequency of the General Assembly leading to aliasing.)

输入信号为正弦波加白噪声，分别用lms，lrs，维纳算法，滤出白噪声中的正弦波。(The lms，lrs filter。)
