自己毕设做的基于三角载波的有源电力滤波器（APF）仿真，可供（apf和pwm整流器设计参考使用）(Do your own complete set of triangular carrier-based Active Power Filter (APF) emulation available (apf and pwm rectifier design reference))

这篇文章是盲信号处理，因为是英文文章，所以大家看内容就好了。(Principal component analysis (PCA) is a mainstay of modern data analysis- a black box that is widely used but poorly understood. The goal of this paper is to dispel the magic behind this black box. This tutorial focuses on building a solid intuition for how and why principal component analysis works furthermore, it crystallizes this knowledge by deriving from simple intuitions, the mathematics behind PCA . This tutorial does not shy away from explaining the ideas informally, nor does it shy away from the mathematics. The hope is that by addressing both aspects, readers of all levels will be able to gain a better understanding of PCA as well as the when, the how and the why of applying this technique.)

一组取值为+/-1的随机序列，每两个数据之间插入3个0，然后将序列通过一个设计好的根升余弦滤波器，并用周期图法和Welch法分别绘制信号的功率谱。再次通过根升余弦滤波器后用stem函数绘图。(A set of values ​ ​ is+ /-1 random sequence inserted between every two data 3 0, then the sequence through a root raised cosine filter designed, periodogram and Welch method to draw the signal powerspectrum. Stem function by root raised cosine filter with drawing again.)

Input data is the MS Excel file, where the table of nodes, table of elements, nodal external loads vector and boundary conditions are stored. After running the mabs2d.m file on the Command Window, the program calculates the stiffness matrix in local coordinates kiL (element i). Once the transformation matrix associated to the element is obtained, the stiffness matrix in global coordinates kiG is also calculated. The table of connectivity is automatically generated for the assembly process and then computes the complete stiffness matrix of the structure.
