近幾年來，發酵程序之控制是相當值得研究與探討的領域。發酵為一種生物轉化程序，若以化學變化之觀點視之，則此種轉化行為的催化劑即為微生物，而進一步由微生物將養份轉化生產出產品。
在生產方面以連續式製程，改善發酵程序的產率（Productivity）為實際工業上之重要課題。大部分連續式系統而言，產出率的考量不外乎產品或是菌種，而過去許多研究大多為考慮菌種產率最大做為最適目標。對產品產率做直接控制亦為可行，但也僅止於單一輸入單一狀態輸出的控制架構，由此操作則僅在於次最適化的操作，實質上而非操作於全域最適化操作點上，因此引發了對於使產出率最適化操作的研究動機，本論文將比較幾種控制方式討論對於最適化操作之影響。

In recent years, fermenter control has been an active area of research and has attracted considerable interest. The fermentation is a kind of biochemical process. If we regard it as a viewpoint of the chemical reaction, then this kind of behavior of microorganism is like a catalyst in chemical reactions, and the microorganism transforms the substrate into products.
Improving the productivity of a fermentation process has long been an important industrial practice. For most of continuous systems, the considerations of productivity are products or biomass. Many studies have been made on improving the steady-state product productivity for continuous fermentation process. The control of productivity is also feasible, but it is only single-input single-output control structure. In fact, the single-input single-output structure is operating on the non-optimal conditions. Therefore, this initiated the research motive in optimal productivity. This study will compare several kind of control modes and discuss the influence of optimal operation.
