pid控制仿真,基于matlab的一个PID的程序，打开就可使用(pid control simulation, based on a PID matlab program, ready to use)

这是周建兴的《matlab从入门到精通》第5章的所有源代码，都可以运行的出来，和课本上的一样，(This is Zhoujian Xing' s " matlab from entry to the proficient," Chapter 5, all the source code, you can run out, and textbooks on the same)

unsupervised local discriminative analysis each column is a data

说明：  对一个简单地系统，设计pid控制器使其控制它的稳定(For a simple system, a PID controller is designed to control its stability.)

单级移动倒立摆建模及串连滞后校正 自动控制课程设计(Single-stage mobile inverted pendulum model and serial lag correction curriculum design automation)

自动解一元二次方程，是一个GUI设计的源码，图形界面没有上传，但是只要相应的控件都可以容易找到(automatically with one yuan quadratic equation, is a source of GUI design, graphical interface without uploads However, as long as the corresponding controls can easily find)

提取mfcc特征，与htk结果一样，并且可以直接用在htk中训练。(extracting mfcc，is the same as htk, and can be training in the htk)

模糊熵，　为解决从信号中提取故障特征难的问题, 介绍了一种新的信号故障特征提取方法—— 多尺度熵( multi-scale entro py, 简称MSE) , 并将样本熵和多尺度熵分别应用于转子故障信号复杂性的度量, 以提取故障特征。试验数据 分析表明, 与样本熵相比, 多尺度熵更能有效地实现转子故障类型的诊断。(A new rolling bearing fault diagnosis approach based onmultiscale permutation entropy (MPE), Laplacian score (LS), and support vector machines (SVMs) is proposed in this paper. Permutation entropy (PE) was recently proposed and defined to measure the randomicity and detect dynamical changes of time series.)

对图像进行逐点计算，并且取最大值和最小值的差值作为该点新的灰度值。 在区别边缘点和非边缘点时，首先确定一个阈值T，若图像中像素点的新 值大于该门限值，则可以初步确定为边缘点，小于T的新值被判断为非边缘点.(Image point by point basis, and taking the maximum and minimum points of difference as the new gray value. Edge in the difference between point and non-edge point, first determine a threshold T, if the image of the new pixel value is greater than the threshold, you can initially identified as the edge point, the new value is less than T have been judged as non-edge point.)

在图像增强的处理过程中采用了小波增强的方法，对模糊图像有一定的作用(In the image enhancement process to enhance the use of the wavelet method, the blurred image to a certain extent)
