| 中文摘要 | 描述封閉型農業環境中溫濕度動態行為之一對線性非耦合向量矩陣微分方程式可用以推導一最佳溫濕度控制系統中之控制器。用現代狀態變數控制理論觀點設計出一比例(P) 及一比例加積分(PI)控制器作為封閉型農業環境中之一最佳溫濕度控制系統。本文採用一線性二次調節器(LQR)推導線性—非時變系統方程式之控制策略。文中針對三種不同之輸出或量測變數設計三種個別之控制系統,系統中考慮起始狀態(脈衝式)與步級干擾作用。最後並以一典型豬舍溫濕度控制設計之過程為例加以介紹。 |
| 英文摘要 | A pair of linear uncoupled vector-matrix differential equations describing the dynamic behavior of temperature and humidity in confined agricultural environments is being used in the development of controllers for an optimal temperature-humidity control system. A proportional (P) and a proportional-integral (PI) feedback controllers have been designed from the view point of modern state variable control theory as an optimal temperature-humidity control system in confined agricultural environments. The linear quadratic regulators (LQRs) with output feedback control of a linear-invariant system equation is chosen for this study. Both impulse and step disturbances are taken into account. Three separate systems have been devised, each differing in the output or measured variables of interest. To illustrate this procedure, the design was applied to control the temperature-humidity in a typical swine building. |
