利用MATLAB实现OFDM的基本功能。效果不错(Use MATLAB to achieve the basic functions of OFDM. Good results)

说明：  GGSO，萤火虫算法实现最优解问题，轮盘赌实现随机数选择(Optimal solution of firefly algorithm)

可以用来识别包装系统的总体参数以及原响应函数的初始相位和振幅(Packaging systems can be used to identify the general parameters as well as the original response function of the initial phase and amplitude)

说明：  哈工大matlab讲义 学习matlab非常珍贵的资料(HIT matlab lecture matlab learning very valuable information)

谢汉龙matlab书籍第五章基本入门功能的实现过程，常用matlab的基础程序(Implementation Xiehan Long basic introductory chapter books matlab function, commonly matlab foundation program)

计算静气动弹性的程序，主要功能包括计算q，和alpha 静稳定性以及表面诱导阻力(Static aeroelastic calculation procedures, the main features include computing q, and alpha-induced static stability and surface resistance)

说明：  EEMD将特殊幅值下的高斯白噪声引入到分解的过程，可以消除上包络和下包络之间存在的拟合误差，从而很好地避免不同尺度下IMF的模态混叠现象，(EEMD can eliminate the fitting error between the upper envelope and the lower envelope by introducing the Gaussian white noise with special amplitude into the decomposition process, so as to avoid the mode aliasing of IMF at different scales,)

里面有三个二维模糊调节器分别实现PID控制器的参数Kp，ki，Kd，的调节。其控制原理：根据前面的偏差e和偏差变化ec将三个模糊控制器FC1,FC2,FC3分别进行模糊化，模糊逻辑推理，解模糊化。最后得到pid控制器参数调节量。(There are three-dimensional fuzzy regulator PID controller parameters Kp, ki Kd, adjust. The control principle: the front of the deviation e and error change ec three fuzzy controllers FC1 has FC2, FC3, fuzzification, fuzzy logic inference, defuzzification. Finally, get the pid controller parameter adjustment.)
