说明：  利用HFSS仿出来S11，S21，导出S11,S21的复数形式，用MATlab调用，就可以计算出介电常数和磁导率(By S11, S21 calculate dielectric constant and magnetic conductivity )

针对六自由度欠驱动四旋翼无人飞行器(QuadmtoruAV)受控模型的复杂非线性问题，提出了一种系统简化方 法，并基于简化后的模型设计了滑模控制器，(a useful papaer for rotor)

粒子群改进算法，有助于学生学习,可以在此基础上改进(Improved particle swarm algorithm to help students to learn, you can improve on this basis)

源信号加多径延时和噪声的仿真，还有其相关性分析，很有用的。(Source signal and multipath delay and noise simulation, and the correlation analysis, very useful )

Design of an Adaptive Nonlinear PID Controller for Nonholonomic Mobile Robot Based on Posture Identifier

带有markov链的灰色系统程序，自己编写的，效果不是特别的明显，但以改小误差(Grey theory model with markov chain to do prediction!)

非常适合计算机视觉方面的研究使用,小波包分析提取振动信号中的特征频率，用MATLAB实现动态聚类或迭代自组织数据分析。( Very suitable for the study using computer vision, Wavelet packet analysis to extract vibration signal characteristic frequency, Using MATLAB dynamic clustering or iterative self-organizing data analysis.)
