电力系统建模控制-串联电容补偿

讲UPF的一个PPT,只对一篇经典文章的总结,我觉得很好,比看文章更能抓住重点.(UPF speaking of a PPT, is only a summary of the classic article, I feel good, better than to see the article focused.)

Otsu method manual implementation in matlabe

拟牛顿迭代法 matlab程序 应用是数字分析课程的matlab代码(ninewton iteration method)

采用了小波去噪的思想，独立成分分析算法降低原始数据噪声，一个师兄的毕设。( Using wavelet denoising thought, Independent component analysis algorithm reduces the raw data noise, A complete set of brothers.)

用matlab仿真轴承故障信号构造轴承故障的仿真信号，其中轴承的固有频率fn=3000Hz , 位移常数y0=5, 阻尼系数ξ＝0.1, 冲击故障发生的周期为0.01s，采样频率fs=20KHz, 采样点数N=4096。要求：根据上述条件构造轴承故障的仿真信号，画出其时域波形及频谱图。(Matlab simulation bearing fault signal)

说明：  有关lfm的一些知识，希望对大家有一定的帮助(Some knowledge about FRFT transformation, we hope to have some help)

nl算法是一个十分好的图像去噪的算法，算法比较容易实现，适合于图像处理方面入门的人学习使用(nl algorithm is a very good image denoising algorithm, the algorithm is relatively easy to implement, suitable for image processing aspects of the entry of people learning to use)
