摘要:科学规划和合理设计课程实验是新建本科院校有效开设《自动控制原理》课程非常重要的一项措施。选择与MATLAB语法兼容的自由软件Octave作为实验平台,设计了自动控制系统数学模型、时域分析、根轨迹分析和频域分析共4个合计12个学时的实验。教学安排上,先课堂讲授相关的理论知识和分析方法,随后通过实验来分析、验证、巩固相关知识点。实验内容中,既有示例性实验,也包括设计性和探索性实验。通过课程实验,激发了学生学习课程的热情和信心,取得了较好的效果。

Abstract: Scientific planning and rational design of course experiment is a very important measure for the newly-established undergraduate colleges to offer the course of automatic control principle effectively. Octave, a free software which is grammatically compatible with Matlab is chosen as the experimental platform, the mathematical model, time domain analysis, root locus analysis and frequency domain analysis of the automatic control system are designed. In the teaching arrangement, the relevant theoretical knowledge and analytical methods are taught in class firstly, and then the relevant knowledge points are analyzed, verified and consolidated through experiments. In the experiment content, not only the example experiment, but also the design experiment and the exploration experiment are included. Through the course experiment, students' enthusiasm and confidence in learning the course have been stimulated and good results have been achieved.
Key words: automatic control principle; experimental teaching; Octave software; simulation experiment; newly-established undergraduate colleges
1 引言
近年來,新建本科院校普遍开设了电子信息、电气自动化等热门专业。《自动控制原理》课程是电子信息专业、电气自动化专业的一门重要的专业基础课程,其具有理论性较强、概念抽象、阐述通用的分析方法、与实际应用有一定的距离、学习难度较大等特点,这些特点对在新建本科院校中开设《自动控制原理》课程,提出了一定的挑战?
根据新建本科院校学生普遍数理基础较薄弱,抽象思维能力较缺乏的现状,除了合理调整教学内容,适当补充课程学习涉及的数理基础知识,大幅度增加控制系统分析方法的实际运用等教学内容外,科学规划和合理设计实验内容,开展与课程讲授内容同步的课程实验,促进学生在实验中不断消化、理解和反复思考课程内容,激发学生学习课程的热情和信心,是非常重要的一项措施。……
