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.

机构：天普大学专业描述该项目正在开发一个模拟电机实验室的软件环境。该环境具有嵌入式智能代理和智能辅导系统，并在没有物理机器实验室的机构提供替代实验体验。学生们正在使用虚拟实验室作为安全的试验台，以便在遇到真实实验室中的机器之前获得经验。该软件提供了一个基于智能代理的虚拟讲师，代表了电力领域的专家。当学生明确要求时，讲师回答问题、提供指导并监督虚拟实验室。图形用户界面(GUI)使学生能够模拟由微分方程式描述的各种电机和驱动，而不需要学生开发计算机程序。直观易用的图形用户界面基于详细的数值方法(用于模拟)，对用户完全透明。该环境允许学生在测试、分析和设计电机的同时学习电机的基础知识。该图形用户界面允许用户通过输入一组新的机器参数，如电阻、电感、惯性等，在运行中修改任何机器。高级用户还可以定义他们自己的电机数学模型。BROADER SIGNIFICANCE该项目正在开发一种智能教学系统，该系统具有参与性、适应性，并为个人学习者量身定做教学。虚拟实验室增加了能够体验电力工程挑战和兴奋的学生数量。该系统提供了接触到各种各样的学生的可能性，这些学生可能无法获得设备，或者不愿进入物理实验室。这项努力还有助于解决学生的安全担忧，他们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。
