In order to ensure the quality of urban water supply,the water supply with frequency conversion and constant pressure is often used. A PID-fuzzy control strategy with Smith predictor is proposed for the constant pressure water supply system, which has the characters of nonlinearity,randomicity,large inertia and big delay.This control strategy combines the advantages of good dynamic response of fuzzy control,high regulation accuracy of PID control and pure lag compensation of Smith predictor.On the basis of retaining the system＇s stationarity,d...
