Abstract
According to the characteristics of nonlinearity and time delay of coagulant dosing in water treatment, it is difficult to realize a good result with traditional control method after analyzing the principle of coagulant dosing. A control scheme for coagulant dosing is proposed by combining generalized predictive control (GPC) algorithm with PID (proportion-integral-derivative) control algorithm. A new performance optimized function is got by predicting a number of controlled system's future outputs. And a reasonable coagulant dosage is computed by optimizing controlled object's parameters in real time. Finally, the scheme is coded with Visual Basic software. It gets a good output with local experiment on automatic control for coagulant dosing, which proves the feasibility of the control scheme.关键词
