pwm整流器的建模仿真，粒子图像分割及匹配均为自行编制的子例程，有详细的注释，双向PCS控制仿真，毕业设计有用，针对EMD方法的不足,采用加权网络中节点强度和权重都是幂率分布的模型，用于特征降维，特征融合，相关分析等。- Modeling and simulation pwm rectifier Particle image segmentation and matching subroutines themselves are prepared, There are detailed notes, Two-way PCS control simulation, Graduation useful For lack of EMD, Using weighted model nodes in the network strength and weight are power law distribution, For feature reduction, feature fusion, correlation analysis.
