• 中文摘要： 本文是針對以鄰二甲苯 (o-xylene) 氧化合成鄰二甲酸酐(phthalic anhydride) 反應器之SISO系統,提出二種推測性控制策略加以探討。推測性控制系統的基本架構是由下列二者結合而成: (1)估算器(estimator)--- 用於估測程序之主要不可測輸出變數; (2) 控制器--- 是由程序模式的倒置 ( inverse)與--- 可調參數濾波器所組成。結果顯示,由非線性估算器發展出之非線性推測性控制(NLIC), 其控制功能優於PI 控制及由線性估算器所發展出之線性推測性控制 (LIC)。且當程序受到較大擾動影響, 以及控制系統有模式誤差存在時,我們必需適當地調整濾波器參數, 以獲得較佳的控制結果。
• 英文摘要： Two distinct types of inferential control strategies for the single-input/single-output (SISO) system of the o-xylene oxidation reactor are introduced. The basic structure of an inferential control system is coupled with an estimator to estimate the primary, unmeasured output of the process from the temperature measurements, and a controller which consists of an inverse of the process model and a filter with adjustable parameters. Simulation results have shown that the Non-Linear Inferential Control (NLIC) system, developed by nonlinear estimator, is better than the Proportional-Integral(PI ) control system and the Linear Inferential Control (LIC) system which are developed by linear estimator. And when the process is influenced by larger disturbances, and a modeling error exists in the control system , we have to properly adjust the filter parameter value in the controller to get better control.
