Diode clamped multi level inverter

说明：  本上传讲解了傅里叶变换与频谱分析之间的关系，通过fft的到信号的频谱图(Explained the Fourier transform of the upload and spectral analysis of the relationship between the fft of the signal through the frequency spectrum)

这是一本简明易学的编码理论方面的书籍，适合于通信电子或其他专业的人自学。(This is a condensed learn coding theory books, suitable for electronic communications or other professional person self-study.)

本代码是基于matlab 的交通路标识别(this text is use matlab for Traffic sign recognition )

non linear optimization technic

燃煤结渣预测，使用支持向量机与模拟退火算法进行优化参数(Slagging Prediction in coal boilers)

matlab新增寻找极值点程序，较老的版本中没有次函数(matlab find new extreme point of procedure, not the older version of the second function)

采用MATLAB中的函数filter2对受噪声干扰的图像进行均值滤波(Using MATLAB functions in filter2 image noise interference by mean filter)

基于matlab的LMS、LMS牛顿算法。用于实现步长K改变对LMS、NLMS的影响。(LMS、NLMS methods based on Matlab. To test the changes when change the K.)

用MATLAB程序软件完成Z-N法对控制器的参数整定，实现P,PI,PID控制器的分别参数整定，并求出控制器的控制参数Kp，Ti，Td。最后绘制出不同控制器控制下的及参数整定前后的单位阶跃响应图进行比较。(MATLAB program software is used to complete the parameter tuning of the controller by Z-N method. The parameters of P, PI, PID controller are adjusted, and the control parameters of the controller Kp, Ti, Td are obtained. Finally, the unit step response diagram before and after parameter tuning is plotted under different controller control.)
