采用永磁同步发电机实现的最大功率追踪，MATLAB建模仿真。(Using permanent magnet synchronous generator to achieve the maximum power point tracking, MATLAB modeling and simulation.)

建立一个实测信号的样本，这里我建立四个随机信号的样本，因为方便显示，蓝色信号为有用信号（正弦信号），黑色的四个信号是随机信号分别与正弦信号叠加形成的实测信号，最后红色的信号为样本的均值信号，即为时域同步平均效果下的信号。(A sample of the measured signal, I created four random signal samples, because it' s easy to display, blue signal is useful signal (sinusoidal signal), four black signal is a random signal with sinusoidal signal is superimposed on the formation of the measured signal. the final red signal is the mean of the sample signal, that is, the average effect of time-domain synchronous signal.)

用MATLAB编写的离散模糊控制程序，结合本程序，我相信能能更快更好的理解模糊控制算法。算法在MATLAB Version: 7.14.0.739 (R2012a)运行无误。 function [FCU_T1,FCU_T2,FCU_T3,FCU_T4]=fuzzy_table(Me,Mec,Mu,UC) Me 隶属度表1 Mec 隶属度表2 Mu 隶属度表3 UC 模糊规则 FCU_T1 重心加权法，输出精确值 FCU_T2 重心加权法，输出离散值 FCU_T3 重心加权法（对隶属度平方），输出离散值 FCU_T4 最大隶属度法 function [R,n,nE,nEC,nU,nfe,nfec,nfu]=fuzzy_relation(Me,Mec,Mu,UC) Me 隶属度表1 Mec 隶属度表2 Mu 隶属度表3 UC 模糊规则 R 表示全体规则构成的模糊关系 n=nfe×nfec nE 模糊变量E的语言值个数 nEC 表示模糊变量EC的语言值个数 nU 表示模糊变量U的语言值个数 nfe 表示E的等级量个数,示例1中其论域为{-6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6} nfec 表示EC的等级量个数,示例1中其论域为{-6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6} nfu 表示U的等级量个数,示例1中其论域为{-7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7} Me 表示E的隶属度表 Mec 表示EC的隶属度表 Mu表示U的隶属度表 UC表示规则表(fuzzy control algorithm（matlab program）)

说明：  利用改进的LM算法实现非线性最小二乘法拟合曲线(Using the improved LM algorithm to realize the curve fitting of nonlinear least square method)

Laser-based的建材研究，报告中附有完整的matlab 源码。(Defective timber is unwanted by the customers therefore it is separated from the normal timbers as soon as it comes out of the sculpting process before it is sent to the market. Therefore the objective of this project is to use a laser-based technique to identify the defects, the type of defects and the quality of the timber.)
