Abstract
The paper addresses automated management policy for anartificial reservoir (dam). Two problems are faced: the control of the dam gate, that is a typical controlproblem, and the definition of the water flow to supply to theuser, that is a decision problem. A mathematicalmodel of the reservoir is deduced, and a PID controller with fuzzygains is designed to operate the dam gate. Ahybrid model of the reservoir is obtained inStateflow/Simulink, and a second fuzzy decision mechanism isimplemented to produce different water releasestrategies. A new cost functional is proposed, able to weightuser's desiderata (in terms of water demand) with water waste (interms of water demand) with water waste (interms of water spills). The parameters of the fuzzy system areoptimized by Genetic Algorithms, veryeffective due to the strong nonlinearity of the problem.
