基于虚拟仪器的自控原理实验教学软件开发

摘要

结合虚拟仪器技术,采用LabVIEW图形化编程语言及其PID工具包、模糊控制工具包、控制设计与仿真工具包,针对温度与液位控制,开发了一套自动控制原理实验教学软件.将自动控制原理运用到Lab-VIEW的虚拟仪器系统进行虚拟实验教学,可以方便、直观地模拟真实实验,提高教学效率、改善实验效果、降低实验费用,有利于更好地培养学生的自主性和创新性.%Combining virtual instrument technology, aiming at temperature and liquid level control based on Lab VIEW (Laboratory Virtual Instrument Engineering Workbench)-graphical programming Language and it's PID toolbox, fuzzy control toolbox and control designed-simulation toolbox, a set of automatic control principle experimental teaching software was developed. Test results show that taking automatic control principle applied to LabVIEW virtual instrument system to virtual experimental teaching can simulate real experiment conveniently and intuitively, increase teaching efficiency and improve experimental effect, moreover to cultivate the students' autonomy and the innovation.
