摘要
PID控制特性是自动原理课程教学中的重点与难点,也是实现PID控制工程化应用的前提和基础.传统的PID控制特性的教学方法是通过理论教学,学生对PID控制特性的理解较为抽象.提出运用磁悬浮小球改进PID控制特性教学方法,将磁悬浮小球重力控制问题贯穿于PID控制特性的课堂教学中,将物理问题转化为数学问题,综合应用时域分析和频域分析手段,实现对磁悬浮小球的重力控制.该教学方法既能够引导学生以工程需求为牵引,引导学生伴问题而思考,又能够提升学生分析问题和解决问题的能力.
PID control characteristics is the key and difficult point in the course of automatic principle teaching,and it is also the premise and foundation to realize the engineering application of PID control.The traditional teaching method of PID control characteristics is through theory teaching,students′ understanding of PID control characteristics is abstract and cannot be combined with the practical engineering application.Using the magnetic levitation ball teaching methods improved PID control features,the control problem of maglev ball gravity through PID control features of classroom teaching,the physical problems into math problems,integrated application of time domain and frequency domain analysis method,analysis of PID controller parameters effect the performance of the system,realize to the gravity of the magnetic suspension ball control.This teaching method can not only guide students to focus on engineering needs,guide students to think with problems,but also improve students′ ability to analyze and solve problems.
