非最小相位系统概念的实例教学

Case Teaching for the Non-Minimum Phase System Concepts

针对在课程教学中学生对抽象的概念难于理解的特点,将具有实际背景的实例引入概念教学中。以非最小相位系统为例,如锅炉汽包水位、飞机等实例,从非最小相位系统概念的定义、非最小相位系统的时域特性以及非最小相位系统概念的物理解释几个方面进行了介绍。这种将学生易于理解的实例引入概念教学中的教学方式,能够充分调动学生的学习兴趣和积极性,帮助学生更好地理解课程教学中的科学概念,增强学生的工程意识,做到理论联系实际。

It is difficult to understand the abstract concept for the students in the lecture.Case study from the practical project is injected into the concept teaching.Several aspects of the non-minimum phase system(e.g.boiler drum water level control system and aircraft pitch control system),which include the concept definition,the time domain characteristic and the physical intuition,are presented.The teaching method for introducing into the practical examples to be easily understood by the students in the concept teaching can adequately activate the student's interest and enthusiasm.It can help the students to catch on the scientific concept,can intensify the student's engineering sense and can make the students to persist in integrating theory with practice.
