模糊PID参数优化

正交频率采样欠采样测量频率处理程序 可以对信号频率进行估计(zhengjiaocaiyang.m)

是Matlab图像处理的原程序代码，适合初学者使用。(Matlab image processing is the original code, suitable for beginners.)

改程序为叶片振动在线检测的速矢端迹法程序，有研究叶片振动在线检测的朋友可以参考(Change the procedure for the blade vibration online testing of hodograph method procedures, research blade vibration online testing can refer a friend)

说明：  三相半桥逆变器并联的下垂控制仿真模型，实现三相半桥逆变器并联的下垂控制仿真(The droop control simulation model of three-phase half bridge inverter in parallel is realized)

some usefull matlab code to practice matlab

说明：  用遗传算法实现的图像分割程序，很好用的程序！(Genetic algorithm is used to realize the image segmentation process, a good procedure to use!)

It is the book about matlab

包括种群初始化、选择、交叉、变异各个子程序，每一部分都作为一个单独M文件。主程序是实现遗传算法网络的训练过程；测试程序可以对训练得到的网络进行结果测试(Including population initialization, selection, crossover and mutation all subroutines, each of which as a separate M-file. Main program is to achieve genetic algorithm network training process test procedures can be trained to get the results of the test network)

matlab编制的随机骨料多边形模型,适合随机骨料的建模和有限元分析(poly rabdom arrevege)

说明：  本程序研究IQ误差对线性调频信号匹配滤波的影响，仿真匹配滤波后信号幅相误差特性，仿真主瓣宽度、旁瓣电平的变化(This program studies the influence of IQ error on matched filtering of chirp signal, simulates the characteristics of signal amplitude and phase error after matched filtering, and simulates the change of main lobe width and side lobe level)
