The system is about simple Vector Control of Permanent Magnet Synchronous Motor. The speed controller is using PI controller and the current controller is using Hysteresis band.

基于单周期控制的升压型有源功率因数校正仿真图( Based on one cycle control boost active power factor correction simulation diagram)

利用fisher方法实现手写体数字多分类识别，采用mnist数据集(simple program using fisher)

Zhou Wang proposed a new idea of Structural Similarity Index (SSIM )for image quality measurement based on the assumption that the HVS is highly adapted to extract structural information from the viewing field. The Mean Structural Similarity Index (MSSIM) contains three parts: Luminance Comparison l(x, y), Contrast Comparison c(x, y) and Structure Comparison s(x, y).
