The urban sewage pumping station has the characteristics of complex lag,and nonlinear.A new sewage pumping station model is proposed by analyzing its characteristics.Then predictive control is proceeding to solve the problems of overflow caused by system's lag response and pumps′ energy optimized control.In order to fit the model,a simulation system is set up.The sampling data,which has been collected from the real sewage pumping station,can be used to have a simulating experiment.The result shows that the model is fit and the method can solve the station's overflow caused by the system's lag characteristic.At the same time,saving energy has also been resolved.
