摘　　要：针对控制工程基础课堂教学中存在的理论知识点较为分散,缺乏实际工程案例分析,从而导致学生对于课程学习感到枯燥,理解各知识点的内容和内在关系存在一定困难等问题,文章探讨了以近场声悬浮(nearfield acoustic levitation, NFAL)为案例的控制工程基础课程教学的设计和应用。通过对NFAL控制系统建立数学模型,获得系统在频域下的响应,进行相应的稳定性分析。通过此案例可以将所学课程相关知识点进行串联,以此助力控制工程基础课程教学。教学实践证明,在教学过程中使用NFAL这一工程案例,可以激发学生的学习兴趣,提高学生对该课程知识点的深刻理解和掌握程度,实现工程教育中培养学生解决复杂工程问题的能力。In view of the problems that exist in the classroom teaching of"Fundamentals of Control Engineering",such as the dispersion of theoretical knowledge points and the lack of actual engineering case study,which leads to the students'feeling of boredom for the course learning and the difficulties in understanding the content and inner relationship of each knowledge point,this paper discusses the design and application of the near-field acoustic levitation(NFAL)as a case study in the teaching of"Fundamentals of Control Engineering".Through the establishment of a mathematical model of the NFAL control system,the response of the system in the frequency domain is obtained,and the corresponding stability analysis is carried out.This case can be used to connect the related knowledge points of the studied course,which can help the teaching of"Fundamentals of Control Engineering"course.Teaching practice has proved that the use of NFAL as an engineering case in the teaching process can stimulate students'interest in learning,improve students'deep understanding and mastery of the knowledge points of the course,and realize the ability of engineering education to train students to solve complex engineering problems.
