PID

压电悬臂梁，本振方程的构建，输出电压，共振频率的选择(Piezoelectric cantilever beam, the construction of the local vibration equation, the output voltage, the selection of resonance frequency)

《测量平差程序设计》（宋力杰编著）一书的源码(" Surveying Adjustment Program Design" (Song Lijie eds) source)

说明：  A SCRIPT + SIMULINK FILE TO COMMAND A TWIN ROTOR MIMO SYSTEM USING MPC METHOD

说明：  求解兰伯特问题的matlab代码，非常好用(The matlab code for solving Lambert problem is very useful.)

说明：  An HTML5 with Music Mobile Phone Shake a Special Effect Code

狼群算法寻优，基于MATLAB采用智能控制算算法寻求最优解(This work proposes a new meta-heuristic called Grey Wolf Optimizer (GWO) inspired by grey wolves (Canis lupus). The GWO algorithm mimics the leadership hierarchy and hunting mechanism of grey wolves in nature.)

说明：  输入一个正整数n(0<n<=0)和一组（n个）有序整数，再输入一个整数x，把x插入到这组数据中，使该组数据仍然有序。(Enter a positive integer n (0 <n<=0)和一组（n个）有序整数，再输入一个整数x，把x插入到这组数据中，使该组数据仍然有序。)
