三相异步电机调速仿真模型，包含变频调速、矢量控制，串电阻调速模型等(Three-phase induction motor simulation , including the Frequency Control, vector control, speed control model series resistor)

说明：  经典的SIFT算法，第一步，选择感兴趣的点；第二步，对感兴趣点进行筛选，确定关键点；第三步，为关键点分配方向；第四步，用多维向量的形式描述关键点(Classical SIFT algorithm, the first step, select the point of interest second step, points of interest were screened to identify key points the third step, the key point for the distribution of direction The fourth step is described with the key in the form of multi-dimensional vector point)

完备图像稀疏表示是一种最新的图像表示模型，采用过完备字典中原子的线性组合形式实现图像的稀疏表示．传统 的过完备图像稀疏表示模型采用重建误差的平方和作为保真项．该保真项没有充分考虑到人眼对图像的感知特性，无法度量图 像中边缘、轮廓、纹理等局部几何结构的变化．本文基于过完备稀疏表示理论思想，建立了新的稀疏性正则化的图像稀疏表示模 型．模型中的正则项约束图像表示系数的稀疏性，保真项采用更符合视觉感知的结构相似性度量．基于正交匹配追踪算法，提出 了基于结构相似度的正交匹配追踪算法．实验结果表示，新的模型能够更好地重构图像的结构信息，获得更好的重建视觉效果． (Image Sparse Representation Model bed StmctIlral SiIIIilarity )
