摘要
本文主要介绍ELVIS在理工科院校控制课程教学中的应用,探讨以虚拟仪器为核心的数据采集系统及其实现信号检测技术的设计方案。利用ELVIS实验板及其自带的函数发生器、数字万用表、示波器等元件,观察到二阶系统的阶跃响应。本实验中,学生自己搭建二阶系统,从响应图上可以更好的理解它的动态特性。实验效果表明,ELVIS平台比传统实验教学装置更具有创新性、实践性,充分调动了学生对实验内容的创造性。
This paper introduces the application of ELVIS in Automatic control course of academies of science and engi- neering. The data acquisition system based on virtual instrument is presented, and design schemes at signal detecting and testing technique course are discussed. It uses function generator, digital multimeter and oscilloscope which are contained in the ELVIS Prototyping Board to observe the step responding of two steps system. In this experiment, students build the system themselves. Form the responds chart student can understand the dynamic characteristic better. The experiment results prove that ELVIS is more innovative and practical than traditional devices, and students can implement more creative experiments on it.
