经验模式分解（EMD）是处理非线性，非平稳信号的一种有效算法。本论文是黄锷先生关于算法的描述(Empirical Mode Decomposition (EMD) is linear and non stationary signals an effective algorithm. Mr. Huang E of this paper is the description on the algorithm)

条带模式的SAR成像算法，很有用！思路清晰，赶紧下载吧。(Strip the SAR imaging algorithm model, very useful! Clear thinking...... )

声音反射的实现，文档里附有运行的图样，即声音反射的波形(voice reflected the realization documentation is enclosed operation of the drawings, that is reflective of the voice waveform)

说明：  最近看到有人提问怎样用FFT实现频谱分析，我认为能够进行到频谱分析的人，对于系统研究的深度基本上已经相当不错了。本人今天做了一个例程，发给大家参考一下。 历程主要内容(signal_analyzer.rar)如下： test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。(The question was asked recently to see the realization of how to use FFT spectral analysis, I think that spectral analysis can be carried out to those who study the depth of the system basically is already quite good. Today I made a routine, distributed to Members for reference. The main contents of the course (signal_analyzer.rar) are as follows: test1.txt the first time as t, 0.001s for the step the second as the system input signal the third as a system output signal. signal_analyzer.m first test1.txt data read into workspace, and then proceed to FFT, analysis of the two signal frequency, output amplitude for input attenuation (db), the output of the input phase difference.)

首先要对样本进行聚类分析，以此来确定模糊规则个数。利用K-means法对样本聚类。(First cluster analysis of samples, in order to determine the number of fuzzy rules. Method using K-means clustering of the sample.)

This is a method called Metoda Fibonacci. And with this method you can find the the optimum way.

说明：  matlab数据采集工具箱应用示例。gui是在matlab7.0.1下设计，matlab7以下版本无法正常运行界面程序。(Matlab Toolbox data acquisition application. Gui is the matlab7.0.1 design, matlab7 following versions are unable to operate normally interface procedures.)

主要运用MATLAB做了永磁同步电机的矢量控制仿真，改仿真系统全面(PMSM VC)
