说明：  基于ziegler-nichols方法的pid整定，包括连续与离散两种方法，是基于稳定性分析的pid整定方法。(based Ziegler-Nichols pid of the whole, including both discrete and continuous method is based on analysis of the pid stability of the entire system.)

说明：  运用光反馈测距的部分程序，运用此程序可实现运用。希望大家参考，并且适当的修改。(The use of optical feedback ranging part of the process, use can be achieved using this procedure. Hope your reference, and the appropriate changes.)

PID的matlab和语言编程算法 适合读读理解PID编程实现(Matlab language programming of PID and PID algorithm is suitable read to understand programming)

还是一个uitableview 变化的demo 大家可以参考一下(Uitableview change or a demo we can reference)

matlab提取图像质心和主轴，使用的是matlab图像处理工具箱函数(extraction matlab image centroid and the spindle, using matlab image processing toolbox functions)

用平面波展开法计算二维声子晶体带隙,可以提取一幅图中想要的目标，能量谱分析计算。( Computation Method D phononic bandgap plane wave, Target can be extracted in a picture you want, Energy spectrum analysis and calculation.)
