本程序是实现电力系统的故障计算程序，故障后会对导纳矩阵进行修正，很好的进行了仿真(This program is a power system fault calculation program, fault admittance matrix will be revised, a good simulation)

这是我从网上下载到的Locally Linear Embedding(LLE)的Matlab代码，希望对研究Manifold Leanring的同事有所帮助(This is I downloaded from the Internet to the Locally Linear Embedding (LLE) of Matlab code, and hope to the study of Manifold Leanring colleagues help )

高斯白噪声的生成程序，采用了小波去噪的思想，小波包分析提取振动信号中的特征频率。( Gaussian white noise generator, Using wavelet denoising thought, Wavelet packet analysis to extract vibration signal characteristic frequency.)

利用随机序列进行间隔控制，选择消息隐藏位(Intervals using random sequence control, select the message hidden bits)

基带信号生成公式，TD的，需要的朋友可以参考一下(Baseband signal is generated formulas, TD, and we need friends can make reference to it)

变频调速是改变电动机定子电源的频率，从而改变其同步转速的调速方法。变频调速系统主要设备是提供变频电源的变频器，变频器可分成交流-直流-交流变频器和交流-交流变频器两大类，目前国内大都使用交-直-交变频器。(Variable frequency speed regulation is the frequency of changing the stator power supply of the motor, thus changing the speed regulation method of the synchronous speed.Variable frequency speed regulation system is the main equipment to provide frequency conversion power of inverter, the inverter can be divided into ac - dc - ac frequency converter and ac - ac frequency converter two kinds big, cross - straight - to pay inverter are mostly used in China at present.)
