基于LabVIEW的自动控制原理虚拟实验系统设计院系专业班级学号姓名指导教师负责教师摘要根据“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。文中分析了目前常见的虚拟实验系统，相应的应用Labview编程语言实现了包含“自动控制原理”课程常见实验的虚拟实验系统。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：虚拟仪器；Labview；自动控制实验；MatlabAbstractOnthebasisofproblemsencounteredinactualexperimentteachingofAutomaticControlTheoryinuniversitiesandneedofexperimentteachingrevolution,anewkindofautomaticcontroltheoryvirtualexperimentsystembasedonLabviewisadvanced.Strong-pointandweadnessofcommonvirtualexperimentsystemsatpresentareanalyzedandavirtualexperimentsystemincludingcommonexperimentsinAutomaticControlTheoryiscompleletedsuccessfullyusingLabviewequivalently.Inaddition,proposalforhardwareexperimentexpansionisputforwand.Atlast,Matlabprogrammingisusedforcomparisonandaccuracycertification.Keywords:virtualinstrument;Labview;automaticcontrolexperiment;Matlab目录第1章绪论..........................................................................................................................11.1背景...............................................................................................................................11.2课题的目的与意义.......................................................................................................21.3Labview的介绍............................................................................................................2第2章设计原理..................................................................................................................42.1一阶系统典型环节虚拟实验系统设计原理...............................................................42.1.1数学模型的建立....................................................................................................42.1.2单位阶跃响应........................................................................................................42.2二阶系统瞬态响应虚拟实验系统设计原理...............................................................52.2.1数学模型的建立....................................................................................................52.2.2单位阶跃响应........................................................................................................52.2.3动态性能指标计算................................................................................................72.3系统校正虚拟实验系统设计原理...............................................................................72.3.1未校正系统的性能指标计算................................................................................72.3.2校正系统的确定....................................................................................................82.4采样系统虚拟实验系统设计原理...............................................................................82.4.1“采样—保持器”组件...........................................................................................82.4.2数学模型的建立....................................................................................................92.5采样系统校正虚拟实验系统设计原理.......................................................................92.6频率特性虚拟实验系统设计原...
