中文摘要 | 本研究探討非線性控制策略於非線性高純度蒸餾塔應用之可行性。在本文中,係 以模式和控制兩種方式處理蒸餾塔的非線性和環路間的偶合作用。低階非線性模式的建立, 增加了非線性簡易去偶控制的可行性,對此幾乎去偶的系統,則可進一步利用線性化迴饋轉 換的方式減少程序的非線性。依此線性系統設計之最佳多環路 PI 控制器,從蒸餾塔的控制 測試結果顯示,非線性控制策略的執行確能使控制效果獲得相當之改善。 |
英文摘要 | Controllability of a nonlinear high-purity distillation column using nonlinear control algorithms is addressed in this study. A modeling and control approach is studied in this paper to handle both nonlinearity and interactions of the column. A low-order empirical nonlinear model is established and utilized to construct nonlinear simplified decouplers, thereby diagonalizing the inputoutput mapping of the column model. Linearizing feedback transformations are then adopted to reduce process nonlinearity for the nearly diagonalized system. Finally, PI controllers are designed on the basis of this transformed linear system. Significant performance improvement in control tests verifies the effectiveness of the proposed nonlinear control approach. |
