SimPowerSystem 的 应 用 介 绍(the introduction of the SimPowerSystem)

基于BP神经网络算法的非线性系统拟合，在matlab中实现BP神经网络非线性拟合算法。(BP neural network algorithm fitting of nonlinear systems)

基于预测控制的永磁同步电机直接转矩控制，利用matlab/simulink平台建立了永磁同步电机直接转矩控制的仿真模型(Based on predictive control of permanent magnet synchronous motor direct torque control of permanent magnet synchronous motor was established based on matlab/simulink platform simulation model of direct torque control.)

实现pca功能的完整matlab程序，很好用,源代码(Pca functional integrity of the implementation of the matlab program, very good, and the source code)

AR人脸库进行DCT变换，然后使用Fisher discriminant analysis 进行特征提取，使用cos分类器进行人脸分类。(AR Face Database for DCT transform, and then use the Fisher discriminant analysis feature extraction, using cos classifier for human face classification.)

一共四个小程序。实现QAM调制，QPSK调制，二元熵函数的绘制，迭代法求离散信道容量。(QAM,QPSK)

COIN DETECTION IS TO IDENTIFY THE GIVEN COIN COUNT IN ANY GIVEN APPLICATION System will automatically delete the directory of debug and release, so please do not put files on these two directory.

Buck PI simulation in matlab

%(第一步加载原始数据并绘图)m文件保存代码;而mat文件保存工作区里面已经加载或计算好的数据 %当前文件夹显示的路径一定要是保存数据和保存代码的文件夹 %“relt”是包含分解结果的矩阵，第一列是原始输入（“gsta（：，2）”），最后一列是趋势。 中间是IMF频率从高到低。 %应该注意的是，由于在eemd.m中，IMF的总数m被指定为log2（N）-1，在某些情况解的线条进行了合并 %因此会比实际分解得到的减少，但在计算周期和表现显著性的时候要将每个模态的周期和显著性计算在内。((The first step is to load the original data and draw) m file saves the code; the mat file saves the data already loaded or calculated in the workspace %% the current folder displays a path that must store data and save the code folder. %"relt" is the matrix that contains the decomposition result, the first column is the original input ("gsta (:, 2)"), and the last column is the trend. The middle is the IMF frequency from high to low. It should be noted that since the total number m of IMFs in eemd. m is specified as log2 (N) - 1, the lines of the solution are merged in some cases % will therefore be less than the actual decomposition, but the period and salience of each mode will be taken into account when calculating the period and performance saliency.)
