六相PMSM传统矢量控制系统的仿真模型，其中六相PWM算法模块采用两个三相SPWM算法模块。(Six-phase PMSM traditional vector control system simulation model, in which six-phase PWM algorithm module uses two three-phase SPWM algorithm module.)

对旧金山海岸的极化SAR数据进行分类。根据图像像素点的散射特性采用Freeman分解对图像进行分类，利用wishart聚类算法聚类。最后得到极化sar数据的分类结果。保证了图像的极化特性和散射特性(Polarimetric SAR data to classify the coast of San Francisco. Freeman decomposition using the image classification, clustering clustering algorithm based on the use of wishart scattering characteristics of the image pixels. The last classification results obtained polarization sar data. To ensure that the polarization characteristics of the image and scattering properties)
