為妥善處理廢水酸鹼中和自動化程序，我們採用虛擬多質子酸來模擬進料組成，以修飾過後的強酸當量來推出此虛擬多質子酸之數學模型，再利用適應控制中的最小平方法來估測出相關參數，以反轉滴定將相關參數線性化，定義誤差並導入控制器中。模擬結果顯示，我們提出的控制器估算法，能夠快速獲得虛擬多質子酸的參數，使系統達到理想的pH控制。

In order to tackle waste water neutralization processes, a single fiction polyprotic acid is used to represent the influent stream. The polyprotic acid model is then derived by the modified strong acid equivalent and model parameters are estimated by on-line least squared method. Using the obtained model parameters, the error of controller is parameterized by an inverse of the titration curve instead of pH values. The computer simulation results show the proposed control algorithms are able to quickly reach the values of the parameters of the fiction polyproitc acid and provide a good performance for pH neutralization processes.
