Abstract

Utilizing measurability of water quality disturbance, a nonlinear regression prediction model-based forward compensation control algorithm with measurable disturbance is proposed for the process of water treatment coagulant dosage. To reject the second disturbance caused by coagulant dosage inverter modification, a mode of double cycle control is presented by combining PFC and PID. Effectiveness of the proposed control strategy is verified through the experimental results of turbidity control of a water factory.
