Previous issue date: 2015-10-15 / Os sistemas de abastecimento de ?gua s?o sistemas complexos e de dif?cil opera??o, possuem diversas configura??es no que diz respeito aos elementos ativos e passivos contidos no sistema. O seu controle e monitoramento ? de suma import?ncia para a opera??o racional do sistema visando sempre atender de forma satisfat?ria ? popula??o minimizando ao m?ximo as perdas h?dricas e tornando o sistema mais eficiente em termos energ?ticos. Os sistemas de abastecimento constituem-se em geral de sistemas cr?ticos, onde n?o h? possibilidades de tempo de parada para testes e simula??es, assim, para realizar o controle de forma adequada ? necess?rio um modelo que represente o sistema de forma satisfat?ria, onde seja poss?vel simular e testar as mais diversas situa??es ?s quais o sistema ? normalmente submetido no dia-a-dia. Neste trabalho ? apresentado o modelo matem?tico do sistema de abastecimento de ?gua (SAA) da Universidade Federal do Rio Grande do Norte (UFRN) contemplando todosos elementos presentes em seu sistema. Tr?s controladores s?o implementados em n?vel de simula??o e tem seus desempenhos comparados: servossistema tipo 1, o controlador preditivo linear e um controlador preditivo n?o-linear. O objetivo ? mostrar que podemos utilizar o modelo do sistema para testes e simula??o de condi??es de funcionamento e sintonia do controlador para obter o melhor desempenho do SAA. / Water supply systems are complex systems and difficult operation. They have different configurations in regard to active and passive elements of the system. The control and monitoring is very important for the rational operation of the system in order meet the satisfaction of the population as much as possible minimizing water losses and make the system more efficient energy. Supply systems are critical systems, there is no downtime possibilities for testing and simulations. To perform the control of tuning you need a model that will best represent the system where you can simulate and test various situations to which the system is typically submitted on a day-to-day. This thesis features the mathematical model of water supply system of the Federal University of Rio Grande do Norte, was modeled all the elements present on your system. Three controllers are implemented in simulation level, and they were compared their performance: servo type 1, the linear predictive controller and a non-linear predictive control. The purpose is demonstrate that we can use the model system for testing and simulation of operating conditions and tuning the controller to best performance of the water supply system.
