• 中文摘要： 為處理批式聚合反應器中溫度路徑的追蹤問題,在本文中提出線上設定點最適化法和控制策略。模擬時採用一套層加熱和蛇管冷卻的批式反應器。在本文中以多輸入多輸出(MIMO)之改良型整體輸入輸出線性化控制(MGLC)結構進行模擬控制的研究。反應器最適化溫度設定點藉由改良的二階段法線上求得。此外,基於能量節省的觀點,推導出線上計算法以決定另一參考路徑。由理論的分析得知,MGLC結構有完美模式倒置的特性。因此,模擬結果充分證實MGLC結構能忠實的追蹤最適化路徑,進而達成我們預期的分子量分布控制目標,如聚合物的聚合度和分散度。
• 英文摘要： An integrated on-line set-point optimization and control strategy is proposed in this work to tackle the temperature trajectory-tracking problem in a batch polymerization reactor. The batch reactor is simulated to be a vessel equipped with heating-jacket and cooling-coils. A multi-input/multi-output control system for the batch reactor is performed by the modified globally linearizing control ( MGLC) structure. The modified two-step method is applied to calculate optimal temperature set-point for the reactor on-line. Additionally, an on-line computation method derived on the basis of minimization of energy is applied to determine another reference trajectory. By theoretical analysis, a perfect model inversion characteristic is embedded in the MGLC structure. Therefore, simulation results confirm that the MGLC structure can track the optimal trajectory tightly and achieve the desired control objectives, i.e., a specified cumulative average chain length and polydispersity of polymer product.
