数字信号处理是电子信息类专业重要的专业基础课,针对电子信息学科之间相互交叉融合、电子信息技术快速发展更新的特点,本文探讨了电子信息和通信工程专业数字信号处理课程的教学,以倒立摆小车的理论分析与系统实现为实例,向学生讲述数字信号处理技术在控制领域中的应用,使学生了解数字信号处理与控制技术的交叉联系,培养和增强学生的学科综合能力和工程实践能力.Z变换是数字信号处理中重要的分析工具,应用Matlab软件,通过分析倒立摆小车的开环系统及反馈闭环系统在Z域内的稳定性,加深学生对Z变换的掌握和应用.以基于嵌入式系统的一级倒立摆小车为实验平台,通过可编程实现小车倒立摆的稳定,让电子信息与通信工程专业的学生建立闭环反馈控制的基本概念,并了解数字信号处理与控制技术两个领域间的相互联系.
Digital signal processing is an important professional basic course for electronic information specialty. In view of the characteristics of electronic information subject interdisciplinary and electronic information technology rapid development and updating, this paper discusses the teaching of digital signal processing course of electronic information and communication engineering, Put the car’s theoretical analysis and system realization as an example to tell students about the application of digital signal processing technology in the field of control so that students understand the cross-linking of digital signal processing and control technology to develop and enhance students’ ability of comprehensive disciplines and engineering practice Z transform is an important analysis tool in digital signal processing.Using Matlab software, this paper analyzes the stability of open-loop system and feedback closed-loop system of inverted pendulum in Z domain and deepens students’ mastery and application of Z transform.Based on embedded The first level inverted pendulum car system is an experimental platform, through the programmable realization of the car pendulum pendulum stability, so that electronic information and communication engineering students to establish the basic concepts of closed-loop feedback control and understanding of digital signal processing and control technology in two areas Interconnected.
