Application of Fuzzy Set Theory in Controlling of Urban Storm Drainage Systems
A fuzzy logic controller - WNC (Water Network Control) was developed for control of urban drainage systems. The objectives are to avoid accidents, flooding, pollutions through combined sewer overflows and excessive operation and maintenance costs. Fuzzy logic was proved to be a promising approach, flexible and easy accepted, because it includes the expert knowledge. Fuzzy control system proposed is robust and also easy to understand and modified. It offers to the operator the possibility to participate directly in the system control, combining the results of the modern optimization techniques with the experience and knowledge accumulated in time by experts. Thus, the control of urban sewer system can be well solved by implementing an intelligent control system, based on available information (fuzzy) and on expert's experience. An important feature of this fuzzy logic system is its capability to elaborate a control decision even in situations that were not considered in the design phase of the urban network
USING MODERN TECHNOLOGIES TO UPGRADE EDILITARY URBAN INFRASTRUCTURE
Adopting the European laws concerning environmental protection will require sustained efforts of the authorities and communities from Romania; implementing modern solutions will become a fast and effective option for the improvement of the functioning systems, in order to prevent disasters. As a part of the urban infrastructure, the drainage networks of pluvial and residual waters are included in the plan of promoting the systems which protect the environmental quality, with the purpose of integrated and adaptive management. The paper presents a distributed control system for sewer network of Iasi town. Unsatisfactory technical state of the actual sewer system is exposed, focusing on objectives related to implementation of the control system. The proposed distributed control system of Iasi drainage network is based on the implementation of the hierarchic control theory for diagnose, sewer planning and management. There are proposed two control levels: coordinating and local execution. Configuration of the distributed control system, including data acquisition and conversion equipment, interface characteristics, local data bus, data communication network, station configuration are widely described. The project wish to be an useful instrument for the local authorities in the preventing and reducing the impact of future natural disasters over the urban areas by means of modern technologies
