LabVIEW-data-acquisition-system
基于LabVIEW的多通道数据采集系统的设计,江苏科技大学硕士毕业论文。全文分为2部分第一部分数据采集硬件的设计中，采用DSP 作为采集卡的CPU，利用USB 接口实现了采集卡与PC 机的通信，整个外围逻辑时序部分用CPLD 控制。第二部分数据管理与分析，作者利用LabVIEW 编写了基于Windows XP的上位机应用程序以及上位机与采集卡之间的通信程序；利用LabSQL 工具包建立了ACCESS 数据库，实现对采集到的数据的存储，并可以查询历史数据。同时系统可以生成报表以及可以对所需要的数据进行打印，并可以对得到的数据进行一些必要的分析，如加窗函数，逐点分析。本文版权归作者所有！下载后产生后果下载者个人负责(LabVIEW-based multi-channel data acquisition system, Jiangsu University of Science Thesis. Paper is divided into two parts the first part of data acquisition hardware design, acquisition card with DSP as CPU, USB interface using a capture card and PC-communication, the entire outer part of the logic timing control with the CPLD. The second part of the data management and analysis, the authors prepared using LabVIEW Windows XP-based PC applications and PC and the communication between the acquisition card program use LabSQL Kit ACCESS database was established to achieve the collected data storage and can query the historical data. At the same time the system can generate the required reports and data can be printed, and can get the necessary data analysis, such as windowing function, point by point analysis.

GPS-Power-Inversion-Algorithm
实现了基于功率倒置算法的 GPS 抗干扰实时系统，并且提出了一种低复杂度的实现算法。 运用 Xilinx 公司
的 Virtex-4 以及 TI 公司的 TMS320C6416T 硬件平台，采用双 FPGA+ 单 DSP 结构来实现整个算法。 实验结
果表明， GPS 信号经过实时抗干扰系统处理后，可以运用普通的接收机进行实时、精确的定位。该系统具有
兼容性好、精度高等优点。(Based on power inversion algorithm，a GPS real-time anti-jamming system composed of the Virtex-4 and
TMS320C6416T hardware platform has been finished. In addition， an improved method which is easy to
implement is also proposed. The algorithm is implemented on the architecture which is made up of double
FPGA+DSP. Experimental results show that the target position which can′t be found without anti-jamming will
be located precisely with ordinary receivers after the GPS signals with blanketing jamming have been passed
through our real-time anti-jamming system. Lots of advantages lies in this system such as：good compatibility，
accurate positioning etc.)

control-IdIq
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.
