An Internet-based Electrical Engineering Virtual Lab: Using Modelica for Unified Modeling

摘要

this paper describes the application of an internetbased electrical engineering virtual lab (iEEVL) using Modelica for unified modeling. In iEEVL, experiments for four courses including circuit theory, analog electronic technique, digital electronic technique and micro-electronics have been implemented using Modelica for both high level and low level modeling. Details about using Modelica for modeling will be discussed. The lab enables the users to design their own circuit and get simulation result simultaneously. Teachers may design new components with Modelica and add to the lab for students' use. Experiments show that Modelica can meet the requirement of unified modeling for electrical engineering courses efficiently. More experiments including MCU and DSP are under developing and will be soon introduced to iEEVL.
