雨污混流管网系统污水溢出最小化方法

Minimize the Overflow of Combined Sewage System

为解决城市排水工程中雨污混流管道存在的污水溢出问题,建立了两节点间管道的离散化的水力学状态空间模型,使用Kalman预测估计递推方程计算增益矩阵和状态值。建立预测模型,预测将来某采样时刻混流管道的污水储量值,经过预测模型输出与观测值之间的误差进行反馈校正,再与参考储量值进行比较,应用二次型性能指标进行在线的滚动优化,计算出当前时刻应加于系统的控制动作,使城市排水雨污混流管网系统污水溢出最小。

In order to solve the problem of combined sewage overflow, the sewer＇s discrete state- space model of the hydraulics and predictive model was established to predict the furore output at sampling moment. Corrected the model by the error between value of observation and prediction. Took a quadratic function of error between the predicted output and the reference trajectory to calculate the best flow rate.
