There is a close connection between the definition of Fourier series and the Fourier transform for functions f which are zero outside of an interval. For such a function, we can calculate its Fourier series on any interval that includes the points where f is not identically zero

关于粗糙集和邻域粗糙集的基本理论和程序算例 本文在原始的邻域粗糙集约简程序基础上做了修改。 压缩文件包括：3个m文件，一个mat文件，一个pdf文档。 这个文档是我自己编写的，关于粗糙集和邻域粗糙集的一些基础知识讲解和邻域粗糙集的基础算例，邻域粗糙集程序使用说明，算例说明。 希望大家能交流学习。如果你没有积分，可以加我qq索取：379786867 (Rough Sets and neighborhood rough set theory and the basic procedures for example in the original article neighborhood rough set reduction procedure done on the basis of the changes. Zip file includes: 3 m documents, a mat file, a pdf document. This document is my own preparation, on rough sets and neighborhood rough set some basic knowledge to explain and neighborhood rough set based numerical example, neighborhood rough set procedures for use, numerical example. I hope we can exchange study. If you no points, you can add my qq Request: 379,786,867)

Control strategies for extracting the three-phase reference currents for shunt active power filters are compared, uating their performance under different source conditions with PI and Fuzzy Controllers in MATLAB/Simulink environment When the supply voltages are balanced and sinusoidal, the two control strategies are converge to the same compensation characteristics However, the supply voltages are distorted and/or un-balanced sinusoidal, these control strategies result in different degrees of compensation in harmonics. The compensation capabilities are not equivalent, with p-q control strategy unable to yield an adequate solution when source voltages are not ideal. Extensive simulations are carried out with PI controller and also with Fuzzy controller for both p-q and id-iq control strategies under different main voltages.
