A practical feedforward control system with fuzzy feedback trim is presented for controlling the dosing strategy of Changhsing Water Purification Plant of Taipei Water Department (TWD). The feedforward move is based on a regression model from successful dosing data between 2001 and 2004. The expert operators' adjusting actions in meeting the settled water turbidity trend and pH values are adopted to establish the fuzzy feedback control rules. A host of field tests have demonstrated the effectiveness of the proposed control strategy.
