DC DC converter (chopper)

此资料中包含5个Matlab GUI 小程序，分别是信号分析、不同图形绘制、极点图绘制、时域频域信号绘制、滑动数字显示。(This data contains five Matlab GUI applets, which are signal analysis, different graphics rendering, pole drawing, draw time-domain frequency domain signal, sliding digital display.)

绘出时域图，在时域上进行分析，提取时域特征值：绝对均值，标准差，有效值，方根幅值，波形指标等等，进行故障特征提取，识别故障(The time domain diagram is drawn and the time domain is analyzed. The time domain eigenvalues are extracted: absolute mean, standard deviation, effective value, square root amplitude, waveform index and so on. Fault feature extraction and fault identification are carried out.)

说明：  集合经验模态分解（EEMD）源程序，内涵实例验证，亲测可用(Ensemble empirical mode decomposition (EEMD) source code)

feature selection using evolutionary algorithm

说明：  Parzen窗法，由样本求概密估计，例为一维正态分布和双峰均匀分布，内附随机数生成的原理说明。( window method, by the sample density estimate for estimated Example for one-dimensional normal distribution and bimodal uniform distribution, random number generator containing a description of the principle.)
