本文件是我们小组参加2013电工杯的数学建模比赛的文件，荣获全国2等奖！我们做的是电力系统分析的题目，内有基于matlab建立的三次平滑统计方法，以及神经网络智能算法，还有就是基于simulink的电力系统仿真程序！内附有程序说明文件。你一定能看懂的，不懂的可以留言给我！(This document is our electrician Cup 2013 team participated in the mathematical modeling of the game files, won the two prize! What we do is the subject of power system analysis, there are statistical methods based on cubic smoothing matlab established and intelligent neural network algorithm, there is a power system based on simulink simulation program! Enclosing a program documentation. You must be able to read and understand can leave a message to me!)

经验模态安装工具包，方便好用，大家学学吧(emd empirical mode toolkit)

说明：  属于真实气体状态方程，可用于计算气体温度、压力和密度。(Calculate physical parameters of a gas, such as pressure, density, and temperature)

FFT sample matlab code

通过simulink图搭建三相逆变器的控制图，采用SVPWM控制技术，是三相逆变器输出电流谐波很小。(Build a three-phase inverter control charts simulink diagram by using SVPWM control technology, is a three-phase inverter output current harmonics is small.)

说明：  In computer science, differential evolution (DE) is a method that optimizes a problem by iteratively trying to improve a candidate solution with regard to a given measure of quality. Such methods are commonly known as metaheuristics as they make few or no assumptions about the problem being optimized and can search very large spaces of candidate solutions. However, metaheuristics such as DE do not guarantee an optimal solution is ever found.

极大似然法，估算已知结点的位置，求出误差(Maximum likelihood method to estimate the location of known nodes, find the error)

跳频信号的短时傅里叶变换时频分析，在脉冲噪声干扰下的拟制噪声处理，并进行参数估计分析效果。(Short-time Fourier transform of frequency hopping signal time-frequency analysis, artificial noise under pulse noise processing, and analysis of parameter estimation results.)
