臺灣博碩士論文加值系統

本文完成恆溫恆濕空調系統熱模型建模，建構恆溫恆濕空調系統結合空調區間之溫濕度的模型。同時，提出「象限控制法則」的控制策略，主要係以風量、加濕量及加熱量等參數調整，以獲得空調區間的恆溫恆濕的控制。最後，使用 MATLAB 應用程式模擬恆溫恆濕空調系統的動態分析，獲得文獻資料的佐證，並以PID 控制與象限控制法則進行穩定性及收斂性的分析及比較。
結果顯示，象限控制法則不論在穩定時間、最大超越量以及穩定誤差的表現上均較PID 控制為佳。這可由在亞熱帶海島型氣候、冬季海島型氣候、低溫乾燥型氣候及沙漠氣候的環境中，PID 控制穩定誤差有±0.1℃的震盪，同時最大超越量隨環境條件不同而異，至於本文之象限控制法則能快速且僅具些微超越量的情形下達到恆溫恆濕的狀
態，並且無擾動現象。

This purpose of this study is to model constant-temperature-constant-humidity air condition system and a novel controller strategy, Quadrant Control Strategy (QCS), is
applied for controlling the temperature-humidity state within the cooling space by modifying parameters of air flow, humidification, and heating. Finally, the comparison between PID and QCS methods is processed by both MATLAB simulations and literature verification for stability and astringency.

The comparison result shows the QCS provides higher performance than PID in settling time, overshoot and steady-state error. The PID simulation results a ± 0.1 ℃ error in predefined environments, such like subtropical island climate, winter island climate, low temperature climate and dry desert climate, while the QCS method handling the constant-temperature-humidity rapidly with a tiny overshoot and no disturbance.
