Fuzzy Optimal Control of Sewage Pumping Station with Flow Concentration

This paper aimed to improve the traditional simple water level control for drainage network. Combining with the prediction model of sewage convergence node, the paper proposed a fuzzy optimal control method, tried to solve: (1) Control lag problem caused by a single pump station isolated control; (2) The problem of pump switchd frequently caused by the conservative control; (3) Minimizing sewage overflow problem at the convergence pump station and (4) Energy saving problem of sewage pumping station operation. The actual example showed that this control method had good effect, and it could be applied to the actual drainage operation.
