摘要:

针对城市排水系统管网中管道发生渗漏这一不确定因素,结合传统圣维南方程组研究渗漏发生时的系统建模与分析问题.分析某段发生渗漏的管道内的水流运动状态,推理计算得出改进后的连续性方程和动量方程.结合我国城市排水系统管网中管道的具体运行情况,对方程组进行线性化,建立以流量为状态的城市排水系统水力学状态空间模型.分析系统稳定性,设计系统状态反馈控制器,通过仿真验证了所提方法的正确性.

Abstract:

he leakage inside the sewer’s pipeline was considered in the urban drainage system. The modeling and analysis of urban drainage system was conducted combined with the traditional SaintVenant equations. The improved continuity and momentum equations were established by analyzing the state of flow in a certain pipeline in the urban drainage system. Combined with the specific condition in the existed urban drainage system, the statespace model of the hydraulics was established to describe the flow inside the sewer’s pipeline through the linearization of the equations. A stability analysis was conducted for the model, and the state feedback controller was designed for the system. The simulation example was given to illustrate the effectiveness of the approach.
