摘要
为了弥补传统实验教学模式的不足,介绍一种使用新型的、面向对象的多领域统一建模语言Modelica进行建模及仿真的电工电子虚拟远程实验室,并详述了其架构及远程实验的操作流程。构建两个子系统——模电实验系统及吹摆控制实验系统。通过调用Modelica标准模型库,实现了模电实验系统的建模;根据模块化建模的思想,对吹摆控制实验系统进行系统分解,利用Modelica编写每个模块的仿真模型,建立了可扩展的系统模型库,并基于该模型库实现了吹摆系统的构建。将两个子系统放在虚拟实验平台上仿真,仿真结果符合理论推算。
To make up for the deficiency of traditional labs, an Internet-based electrical and electronic virtual remote laboratory was introduced, in which a unified object-oriented language Modelica was used for modeling and simulation. The architecture and the internal mechanism of the virtual remote lab operation were elaborated. Two subsystems, the analog circuit system and the plate angle control experiment system were introduced as examples. The modeling of the analog circuit system was achieved by calling the Modelica standard library. The plate angle control experiment system was divided into modulars and the simulation models of each modular were built by Modelica. The scalable model library was established, and on the basis of it, the plate angle control experiment system was constructed. The two subsystems were simulated on the virtual platform and the results were consistent with theoretical calculations.
