An Optimal Fuzzy Approach to Automated Reservoir Management
نویسندگان
چکیده
This paper deals with water resource management problems faced from an Automatic Control point of view. The motivation for the study is the need for an automated management policy for an artificial reservoir (dam). Two problems are addressed in the article: the control of the dam gate, that is a typical control problem, and the definition of the water flow to supply to the user, that is a decision problem. In particular, a mathematical model of the reservoir is deduced, and a PID controller with fuzzy (nonlinear) gains is designed to operate the dam gate. Moreover, a hybrid model of the reservoir is considered and implemented in Stateflow/Simulink, and a second fuzzy decision mechanism is implemented in order to produce different water release strategies. A new cost functional is proposed, able to weight user’s desiderata (in terms of water demand) with water waste (in terms of water spills). The parameters of the fuzzy system are optimized by employing Genetic Algorithms, which have proved very effective due to the strong nonlinearity of the problem. Copyright c ©2005 IFAC.

Intelligent reservoir characterization using seismic attributes and hydraulic flow units has a vital role in the description of oil and gas traps. The predicted model allows an accurate understanding of the reservoir quality, especially at the un-cored well location. This study was conducted in two major steps. In the first step, the survey compared different intelligent techniques to discover ...
متن کاملDETERMINATION OF OPTIMAL HEDGING RULE USING FUZZY SET THEORY FOR MULTI-RESERVOIR OPERATION
To deal with severe drought when water supply is insufficient hedging rule, based on hedging rule curve, is proposed. In general, in discrete hedging rules, the rationing factors have changed from a zone to another zone at once. Accordingly, this paper is an attempt to improve the conventional hedging rule to control the changes of rationing factors. In this regard, the simulation model has emp...
