Abstract. This paper describes an interdisciplinary design
project which was done under the author’s supervision by a
group of four senior students in the Department of Engineering
Science at Trinity University. The objective of the project
was to develop a temperature control system for an air-filled
chamber. The system was to allow entry of a desired chamber
temperature in a prescribed range and to exhibit overshoot
and steady-state temperature error of less than 1 degree
Kelvin in the actual chamber temperature step response.
The details of the design developed by this group of students,
based on a Motorola MC68HC05 family microcontroller, are
described. The pedagogical value of the problem is also discussed
through a description of some of the key steps in the
design process. It is shown that the solution requires broad
knowledge drawn from several engineering disciplines including
electrical, mechanical, and control systems engineering.


摘要：
圣安東尼奧，TX78212本文介紹了一個跨學科的設(shè)計項目，該項目是根據(jù)作者的監(jiān)督工作由組四個工程系大四學生科學在三位一體大學。該項目的目標是開發(fā)一個充滿空氣的溫度控制系統(tǒng)室。該系統(tǒng)允許所需室入口在規(guī)定的溫度范圍，并表現(xiàn)出沖和穩(wěn)態(tài)小于1度的溫度誤差開爾文在實際室溫度階躍響應。設(shè)計的細節(jié)制定本組學生，在摩托羅拉MC68HC05系列微控制器為基礎(chǔ)，描述。問題的教學價值也討論通過在一些關(guān)鍵步驟的描述設(shè)計過程。結(jié)果表明，該解決方案需要廣泛從幾個工程學科包括制定知識電氣，機械和控制系統(tǒng)的工程。
