模糊控制在减少合流制管道污水溢出中的应用

合流制管道污水溢出问题一直存在于国内外很多大城市中,引起了严重的环境污染,是个亟待解决的问题。合流制管道系统是典型的大规模系统,很难用传统的控制方法来防止污水溢出。该文在分析合流制管道系统实际操作者的操作经验基础上,以典型的三泵站合流制排水系统为例,提出了模糊控制理论应用于合流制排水管道污水溢出最小化的方法,该方法能很好地解决污水溢出问题,并有效降低水泵站能耗。文中既简要概括介绍了模糊控制的基本原理,又详细阐述了模糊控制器的设计过程,为合流制管道系统的实时过程控制从手动向自动转化奠定了基础。

Minimization of CSO using fuzzy control

The problem of CSO(combined sewer overflows) exists in many megapolis, it causes serious environment pollution, and should be solved quickly. In order to prevent sewage overflows, Combined sewer systems are typical large-scale systems and have proven to be hard to control using conventional control technologies. On the basis of analysis of combined sewer systems operator's experiences, an method that minimization of CSO using fuzzy control theory is presented for a representative three-reservoir system, this method can resolve the problem of sewer overflows, and reduce the use of electric power in pump stations effectively. Not only the basic theory of fuzzy control is introduced briefly, but also the design process of fuzzy controller is presented, it founded the transformation from hand-act to automation for the real time control of combined sewer systems.
