本研究主要針對饋料批次生化反應器及管式流動反應器進行最佳化控制問題的探討，首先引用Pontryagin最小化原理來定義最佳化問題，並運用極限控制概念，以階段性方式控制系統，再藉由奇異值控制理論避開複雜的兩端點邊界值問題。
依上述最佳化架構下，分別對饋料批次生化反應器及管式流動反應器進行最佳化的設計，最後對系統進行韌性測試，運用非線性模式預測控制進行干擾消除，將系統維持在最佳狀態。

This research mainly aims at probing into the optimal control problem (abbreviated as OCP) of fed-batch bio-reactor and tubular flow reactor. First of all, the minimum principle of Pontryagin are introduced to define the optimal control problem. Moreover, the concept of Extremal control is utilized in the performance. With the control of bang-bang type, the system would be manipulated. In addition, Singular control theory is applied to avoid the complex problem of the two point boundary value problem.
According to the optimal construction indicated above, the optimal design of fed-batch bio-reactor and tubular flow reactor would be operated individually. Finally, the study proceeds the robust test in order to maintain the best condition of this system by using nonlinear model predictive control which can remove the disturbance, and to maintain the system at the optimal condition.
