A Realistic Intelligent Multimedia Virtual Laboratory for Power Applications

机构：天普大学项目简介这个项目正在开发一个软件环境来模拟电机实验室。该环境有一个嵌入式智能代理与智能辅导系统相结合，并提供了一个替代的实验经验，在没有物理机器实验室的机构。学生们使用虚拟实验室作为一个安全的试验台，以积累经验之前，遇到机器在真实的实验室。该软件提供了一个基于智能代理的虚拟讲师，代表电力领域的专家。教师回答问题，提供指导和监督虚拟实验室-当学生特别要求时。图形用户界面（GUI）使学生能够模拟由微分方程描述的各种电机和驱动器，而无需学生开发计算机程序。直观且易于使用的GUI基于详细的数值方法（用于模拟），对用户完全透明。环境允许学生学习电机的基础知识，而他们测试，分析和设计它们。GUI允许用户通过输入一组新的机器参数（如电阻器、电感器、惯性等）来“实时”修改任何机器。高级用户还可以定义自己的电机数学模型。更广泛的意义该项目正在开发一个智能辅导系统，该系统具有吸引力、适应性强，并为每个学习者量身定制指导。虚拟实验室增加了能够体验电力工程挑战和兴奋的学生人数。该系统提供了接触各种学生的可能性，否则他们可能无法获得设备或不鼓励进入物理实验室。这项工作还有助于解决学生的安全问题，这些学生可能会因为实验室中遇到的高电流和高电压而避免参加电力工程课程。

INSTITUTION: Temple UniversityPROJECT DESCRIPTIONThis project is developing a software environment to simulate an electrical machines laboratory. The environment has an embedded intelligent agent coupled with an intelligent tutoring system and offers an alternative experimentation experience at institutions that do not have a physical machines laboratory. Students are using the virtual laboratory as a safe test bed to garner experience prior to encountering machines in a real laboratory. The software offers an intelligent agent-based virtual instructor that represents an expert in the power field. The instructor answers questions, provides guidance and supervises the virtual laboratory - when specifically requested by the student. The graphical user interface (GUI) enables students to simulate various electrical machines and drives described by differential equations, without requiring students to develop computer programs. The intuitive and simple-to-use GUI is based on detailed numerical methods (for the simulation), which is entirely transparent to the users. The environment allows students to learn the basics of electric machines, while they test, analyze and design them. The GUI allows users to modify any machine "on-the-fly" by entering a new set of machine parameters, such as resistors, inductors, inertia, etc. Advanced users also have the ability to define their own mathematical model of an electrical machine.BROADER SIGNIFICANCEThe project is developing an intelligent tutoring system that is engaging, adaptable, and tailors instruction to individual learners. The virtual laboratory increases the number of students who can experience the challenges and excitement of power engineering. The system offers the potential for reaching a diverse range of students who might not otherwise have access to equipment or are discouraged from entering a physical laboratory. The effort also helps address safety concerns of students that might avoid taking power engineering courses because of the high currents and voltages encountered in the labs.
