在Matlab simulink仿真环境中，用恒压法实现MPPT模型仿真。(IN Matlab simulink simulation environment, MPPT model simulation using the constant voltage method.)

模糊熵，　为解决从信号中提取故障特征难的问题, 介绍了一种新的信号故障特征提取方法—— 多尺度熵( multi-scale entro py, 简称MSE) , 并将样本熵和多尺度熵分别应用于转子故障信号复杂性的度量, 以提取故障特征。试验数据 分析表明, 与样本熵相比, 多尺度熵更能有效地实现转子故障类型的诊断。(A new rolling bearing fault diagnosis approach based onmultiscale permutation entropy (MPE), Laplacian score (LS), and support vector machines (SVMs) is proposed in this paper. Permutation entropy (PE) was recently proposed and defined to measure the randomicity and detect dynamical changes of time series.)

说明：  100kV光伏并网平均模型 MPPT使用扰动观察法(Average Model of 100 kV Photovoltaic Grid Connection MPPT uses perturbation observation method)

改进平方根法求解对称正定线性方程组，用matlab编写，可以在一定程度上提高求解效率。其中MRoot_squaring.m为原做法，sparse_cmp.m为二维等带宽存储，Moot_zonal.m为二维等带宽存储的平方根法求解(To improve the square root method to solve symmetric positive definite system of linear equations using matlab to prepare, to a certain extent improve the efficiency of solving. MRoot_squaring.m which the original approach, sparse_cmp.m for the two-dimensional, such as memory bandwidth, Moot_zonal.m for the two-dimensional, such as the square root of bandwidth storage method)

说明：  利用harris所做的角点提取程序，具有一定的参考价值。(Made by harris corner detection procedures, with some reference value.)

齐次坐标变换有很多形式，本程序证明采用不同形式时对应的转换矩阵不同(homogeneous coordinate transformation)
