PID控制器的源码设计，一个比较简答易学的程序代码(PID controller source design, a relatively short answer to learn of the program code)

说明：  matlab的噪声模型，在原有噪声模型的基础上作出了一些改进。(matlab noise model, noise model on the basis of the original made some improvements.)

用MATLAB实现对图形图像的处理，图像的平滑滤波。(Realized by MATLAB graphics image processing, image smoothing.)

参数辨识问题，本程序是基于RLS法的参数辨识最新解法(Based on the RLS parameter identification)

主成分分析法将图像分为低秩部分和稀疏部分(Principal Component Analysis (PCA) divides images into low rank and sparse parts)

用MATLAB回归非线性模型参数,用MATLAB回归非线性模型参数(Linear regression model parameters with MATLAB)

是matlab程序，关于太阳能ＭＰＰＴ的三种不同方法的，自己可以调试一下看看，希望有用。(Matlab program is on three different solar MPPT methods, they can debug it and see, hope useful.)

提出了一种鲁棒的多水印嵌入与检测算法,该算法基于小波域,且提取水印时不需要原始图像,保护了原始图像的安 全。在该多水印算法中,提出并使用了一种将密码学和常规的数字水印制作方法- - - 叠加法和量化调制法,有机结合起 来的新的方法,在水印嵌入时,不同的水印,生成与该水印相关的不同的密钥,在进行水印的提取时,用不同的密钥和待测的 图像提取出相应的水印。通过将密钥向第三方注册,可以获得对原始图像的所有权。(A robust multi-watermark embedding and detection algorithm, the algorithm based on wavelet domain, and extract the watermark without the original image, protect the safety of the original image. In the multi-watermarking algorithm, will be presented and used a conventional cryptography and digital watermarking production method--- superposition method and quantify the modulation method, combine the new method, the watermark embedding different watermark, associated with the watermark generating different keys, making extraction of the watermark when tested with a different image key and the corresponding extracted watermark. By the key to a third party registration, can be obtained ownership of the original image.)

二维卷积过滤器 卷积是一种像素过滤器 用像素本身以及邻近像素的加权平均值来替换这个像素(Two-dimensional convolution filter Filters of the convolution is a weighted average of the pixel and the neighboring pixels in the pixel itself, the pixel is replaced)
