无传感器永磁同步电机仿真，基于滑膜变结构控制(Sensorless permanent magnet synchronous motor simulation, based on variable structure sliding mode control)

提取图像特征点，提取的效果较好，程序由matlab编写，简单易懂，可作为参考。(Extract image feature points extracted better, the program written by matlab, easy to understand, can be used as a reference.)

录制一段自己的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用窗函数法和双线性变换设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号；最后，设计一个信号处理系统界面。(Section of their own voice recording signal, and recording the signal sampling draw sample after the speech signal time-domain waveform and frequency spectrum given filter performance indicators, using a window function method and bilinear transformation design of filters, and draw the frequency response filter then use the filter of their own design for the signal acquisition filtering, after filtering the signal to draw the time-domain waveform and spectrum, and filtering of signals before and after contrast, analysis of signal changes playback voice signal Finally, the design of a signal processing system interface.)

说明：  此为MATLAB写的关于2DPSK调制解调的程序并且通过验证可以实现，程序对2DPSK的算法都有相应的程序(This is written in MATLAB on 2DPSK modem to verify the procedure can be achieved through the procedures of the algorithm 2DPSK procedures have corresponding)

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.)

matlab下的k中心点聚类算法，matlab内置仅有k均值聚类算法(k under the center clustering algorithm matlab, matlab built-k-means clustering algorithm only)
