本文首先介绍了逆变电源的发展现状及趋势。文中分析了适合数字控制的基于DSP 处理器 TMS320F2812 和智能功率模块（IPM）的逆变器硬件；介绍了 SVPWM逆变技术的基本理论，详细推导出了五种具体的 SVPWM 实现模式，并通过比较说明不同实现模式的优缺点，得到本课题采用的一种优化模式，设计研究了基于 SVPWM控制方式的软件；介绍了 Q 格式的基本理论，在程序中变量间的运算采用 Q 格式，提高了系统数据运算的速度和精度，实现了在定点处理器上进行高性能的浮点运算；详细讨论了片上模数转换模块的转换误差来源及影响，研究了减小转换误差的方法，采用了软件方法来对转换结果进行实时校正，提高了模数转换的准确度。(In the first, the current situation and development trends of the inverters are presented in the paper. Following is the analyses of hardware of the inverter suiting for digital control based on digital signal processor TMS320F2812 and the intelligent power module(IPM) the basic theory of space vector pulse width modulation (SVPWM) is introduced, five specific SVPWM modes of implementation are educed detailedly, following by the comparison which shows the advantages and disadvantages of different patterns, an optimization mode is got which is used in this project, and the software is designed based on SVPWM control pattern the basic theory of Q format is presented, variable Q format is adopted during the procedure for the calculation which improves the operation of the system data speed and precision, achieving the targeted processor for high-performance floating-point operation in the fixed-point DSP the error sources and effects of the on-chip analog-to-digital conversion module(A)

针对TI公司的TMS320F28335这一款DSP的ePWM模块开发出的程序。该程序的功能是：在ePWM3A和ePWM3B上输出带死区的互补PWM波形(Develop procedures for TI' s TMS320F28335 This is a the DSP' s ePWM module. The function of the program is: complementary PWM waveform output with dead-on ePWM3A and ePWM3B)

PMSM弱磁控制，C语言编写，适用于初学者，欢迎指教(PMSM Weak Field Control)

在进行图像处理相关DSP编程时，需要移植opencv到CCS平台。作者提供了将Opencv（1.0版本）的cxcore函数库移植到CCS的静态链接库cxcore.lib，以及其生成工程，该例程经作者编译听通过（ccs3.3版本）。由于工程中产生的obj文件和lib文件太大，在工程中已经将其删除，读者在使用时，只需要对工程重新编译即可。最后将生成的cxcore.lib添加到CCS的工程中即可（不要忘了添加相应的头文件），由于cxcore.lib一般和cv.lib配套使用，读者在下载cxcore.lib时也一并将cv.lib下载。作者也提供了将cv.lib与cxcore.lib添加到工程中的实验例程，并且该例程编译通过。也希望读者在该论坛找到该例程将其一并下载，配合使用。(During image processing DSP programming related, it is necessary to transplant opencv CCS platform. The authors provide the Opencv (1.0 version) of cxcore CCS library ported to the static link library cxcore.lib, as well as its generation project, the routine is compiled by the author to listen through (ccs3.3 version). As the project has generated obj files and lib file is too large, the project has been to remove it, the reader is in use, only need to recompile the project. Finally, the resulting cxcore.lib added to the CCS project can (do not forget to add the appropriate header files), as cxcore.lib general and cv.lib supporting the use of the reader and download cxcore.lib when a cv . lib download. The author also provides a cv.lib cxcore.lib added to the project with the experimental routine, and the routine compile. I hope readers find in this forum and download one of the routine, with the use.)

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. 将中文译成英语 All copyright of the article!
