A Study on Optimal Control of the New Type Interceptor Sewer System
-
摘要: 分析了一种新型截流式城市污水系统的运行机理及相关因素,建立了系统最优控制模型.研究结果表明,可以运用线性规划方法求得系统各分流室各时段内的最优流量分配,从而确定相应的最优控制状态.算例结果显示,所有时段内各分流室的最优控制状态与其位置及相应的污染度系数显著相关.研究成果对现有的或在建的截流式污水系统的有效运行有指导意义.Abstract: In this paper a new type interceptor sewer system is introduced and a model is establishedto solve the problem of optimal controlby analysing the facts on the interceptor sewer system and a Fortran program is produced for this model.This paper shows that the optimal control states can be determined by working out the optimalflow rates by means of the linear programming.A simple sewer system is conside red in order to examine the model as well as the program and the result is verysensible with interception points and the concentration weight coefficients overtime.The results farther highlight some practical applications for the existing interceptor sewer systems or the systems under design.
