《自动控制原理》虚拟实验系统开发 The development of virtual lab system for automatic control theory PAGE III 摘要 根据《自动控制原理》课程实验教学在高校实验实践中遇到的困难和实验教学改革的需要，本文提出了建立基于LabVIEW的自动控制虚拟实验系统方案。运用虚拟仪器代替传统仪器，既节约实验室建设成本，又可以得到良好的实验效果。另外，该系统可以调动学生积极性，培养创新精神，加强实践动手能力的培养 本文首先分析了虚拟仪器的构成、分类与应用，选择图形化软件LabVIEW作为开发环境；其次，提出基于LabVIEW的自动控制原理实验系统的方案，包括系统结构、功能和性能特性以及设计流程和方法，并逐一实现各子实验系统。最后，利用Matlab语言编程进行对比分析，进行正确性验证。 关键词：自动控制系统，虚拟仪器，MATLAB ABSTRACT On the basis of problems encountered in actual experiment teaching of Automatic Control Theory in universities and need of experiment teaching revolution,a new kind of automatic control theory virtual experiment system based on LabVIEW is advanced.Using the virtual instrument to instead of the traditional instruments, namely, saving the laboratory construction costs, but also can be a good experiment. In particular, the practical ability to engage students and cultivate a spirit of innovation can be strengthen. Firstly, the Virtual Instrument is briefly introduced in the paper, including the form, classification and the application. Then the graphics mode software LabVIEW is selected as development environment. Secondly, the project of experiment system of automatic control theory based on the LabVIEW is given; including system structure, function and performance characteristics as well as the design process and methods, then the experimental sub system is designed one by one. Finally,MATLAB programming is used for comparison and accuracy certification Keywords: automatic control system,virtual instrument,MATLAB 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc357547097 摘要 = 1 \* ROMAN I HYPERLINK \l _Toc357547098 ABSTRACT = 2 \* ROMAN II HYPERLINK \l _Toc357547099 1 绪论 PAGEREF _Toc357547099 \h 1 HYPERLINK \l _Toc357547100 1.1 课题研究的背景 PAGEREF _Toc357547100 \h 1 HYPERLINK \l _Toc357547101 1.2 课题研究的目的与意义 PAGEREF _Toc357547101 \h 1 HYPERLINK \l _Toc357547102 2 系统总体方案论证 PAGEREF _Toc357547102 \h 2 HYPERLINK \l _Toc357547103 2.1 本课题的设计任务 PAGEREF _Toc35
