• 中文摘要： 本文探討線性控制策略於非線性高純度蒸餾塔應用之可行性,所提全PI多變數控制策略可維持一模擬之高純度雙成分蒸餾塔產物嚴格的控制。高純度分離所造成不定性之預估及後續具韌性之對角線及全PI控制器設計均有詳盡的說明,由於所提控制策略仍保有線性控制架構的特徵,因此全PI之控制系統能以發展完整之線性韌性技術加以設計和分析,測試結果顯示此種控制策略在非線性控制上,能提供遠較一般非線性控制定律簡易之方法。
• 英文摘要： Controllability of a nonlinear high-purity distillation column using linear control algorithms is addressed in this paper. A multivariable controller, in the form of full PI, is found to be highly effective in maintaining tight control of both end products of a simulated binary distillation column. Uncertainty estimation and subsequent design of robustly stable diagonal and full PI controllers are presented in detail. Due to the fact that the proposed control algorithm retains the fundamental characteristics of a linear controller structure, it can easily be designed and analyzed with available linear robustness techniques. It is believed that full PI controller can provide an attractive alternative in nonlinear process control over sophisticated nonlinear control laws.
