溫度控制在化工程序中不是非常困難的控制,但如何調諧溫度控制器,使用者還是必須學習,若透過真實系統來學習,不符合經濟效益及學習效率,最好的學習方式是藉助模擬程式。本研究將開發個人電腦上可使用之溫度程序即時動態模擬視窗程式,溫度程序由回饋、串級、前饋三種控制策略加以控制。本研究期望透過圖形化之人機介面,讓本程式之操作更能接近真實系統。 模擬程式是利用Visual Basic 2005來撰寫。首先建立人機操作介面及控制項之副程式模組,接著建立實驗數據、應答圖等附加功能,最後再整合成整個程式。 使用開發完成之模擬程式,做回饋、串級、前饋三種控制策略之比較研究,結果發現,開發完成的溫度程序之回饋、串級、前饋控制即時動態模擬視窗程式,已具備提供學習學習比較各種不同控制策略的功能。
Although temperature processes are not very difficult tuning processes in the chemical plants, new incomer should learn how to tune the temperature controller. According to the economic benefits and learning efficiency, the best way that the beginners study them is through the process simulator. The research will develop a real time dynamic simulation window programming of temperature processes. The control strategies are feedback control, cascade control and feedforward control. Through graphic and Man-Machine interface design, all the operations of the control system could be the same as the real system is hoped. Visual Basic 2005 programming language was used to develop the programming. Finally, the simulation temperature process controlled by three different strategies was studied. As a result, our program can be used for beginners to study and compare the different control strategics of temperature process.
