• 中文摘要： 本文探討三種輸出回饋控制器包括比例增益控制(PI),以狀態空間表示之非線性內部模式控制(NIMC),以及所提動態型輸出回饋控制器(DOFC),藉由一發生續攪拌反應器內之放熱平行反應例子,目的是要提供一些比較性結果。若考慮程序裝置上延遲與啟始操作條件為已知,針對具多重穩態程序時利用Z-N調諧方法設計PI控制器是可達設定點無誤差及干擾消除。再則,所謂NIMC方法因包含一開環路模式,所以在做大範圍輸出循跡控制會有明顯退化。至於DOFC方法乃是利用Fliess'線性化方式設計非線性似 Luenberger觀測器予結合成動態型輸出回饋控制。藉由完整理論分析,發現所謂DOFC設計方法對系統不確定及裝置上延遲是具有韌性的。
• 英文摘要： This paper presents several comparative results for three output feedback controllers, i.e., proportional- integral (PI) control, state-space formulation of nonlinear internal model control (NIMC), and dynamic output feedback control (DOFC), for exothermic parallel reactions in a continuously stirred tank reactor. Under the known measurement delay, initial operating points, and multiplicity behavior of the process, the linear PI controller with the Z-N tuning method can provide the no offset performance for set point change and disturbance rejection. Since the NIMC design incorporates an open-loop model, the output regulation of an unstable system may be obviously degraded within large operating region. The DOFC design which combines a dynamic state feedback through Fliess' linearization algorithm with a nonlinear Luenberger- type observer can provide a smooth and stable regulation response in an arbitrary operating region. With the aid of a complete theoretical analysis , it is also found that the DOFC design is robust to uncertainty and measurement delay.
