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 Engineer-ing 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 cham-ber temperature in a prescribed range and to exhibit over-shoot and steady-state temperature error of less than 1 de-gree 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 dis-cussed 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 includ-ing electrical, mechanical, and control systems engineering.

摘要 介紹了一個(gè)跨學(xué)科的設(shè)計(jì)項(xiàng)目，由一組的四名學(xué)生在圣三一大學(xué)的 Engineer¬ing 科學(xué)系作者的監(jiān)督下完成。該項(xiàng)目的目標(biāo)是發(fā)展空氣 filled 室中的一種溫度控制系統(tǒng)。允許在規(guī)定的范圍內(nèi)所需的 cham¬ber 溫度的條目，并展示 over¬shoot 和穩(wěn)態(tài)溫度誤差小于 1 的學(xué)位開(kāi)氏實(shí)際室溫度階躍響應(yīng)中的系統(tǒng)。描述了由這批學(xué)生，摩托羅拉 MC68HC05 的家庭單片機(jī)開(kāi)發(fā)設(shè)計(jì)的詳細(xì)信息。教學(xué)價(jià)值的問(wèn)題也被 dis¬cussed 通過(guò)一些設(shè)計(jì)過(guò)程中的關(guān)鍵步驟的說(shuō)明。它是顯示該解決方案需要來(lái)自 includ¬ing 電氣、 機(jī)械、 的幾個(gè)工程學(xué)科的廣泛知識(shí)，并控制系統(tǒng)工程。
