Sistema de controle adaptativo aplicado a um sistema de distribuição de água com ênfase na eficiência energética

Reducing pressure in a water distribution system leads to a decrease in water leakage, decreased cracks in pipes and consumption decreases. Pressure management includes an advanced type called remote real-time control. Here pressure control valves are controlled in real-time in such a way to provide set optimal pressures mostly at remote consumer locations. A hydraulic valve is expected to minimize problems with transients, although the study also applies to other valves. The control is done by using a controller which typically depends on tunable parameters, which are laborious to determine. A parameter-less controller is simpler because there are no parameters to tune. Such an existing P-controller based on the flow in a pressure control valve being known, is enhanced from assuming constant flow to be valid for variable flow. This novel parameter-less controller performs significantly better than the former P-controller. Several recently proposed controllers, which were studied numerically, are compared: The two parameter-less controllers, and two parameter-dependent controllers. The new parameter-less controller performs either better or worse than the most optimally tuned parameter-dependent controllers.

Low and constant pressure can be maintained throughout a water distribution system by setting the pressure at remote consumer locations and using the pressure to control the speed of a variable speed pump (VSP). The prospect of incorporating hydraulics theory into a controller is investigated, with the goal of improving on generic controllers. Five new controllers are proposed here, four of which depend on hydraulics theory. These controllers, which set the speed of the VSP, are investigated numerically. A parameter-dependent controller that does not require the flow in the pump to be known is developed and shown to significantly improve on the performance of conventional (parameter-dependent) proportional control (PC). Next, a parameter-free controller that requires the flow in the pump to be known is proposed and shown to outperform PC, even though PC has a tunable parameter, and perform comparably to the best new parameter-dependent controllers. The parameter-dependent controllers (when optimally tuned) perform best overall. The efficacy of many of the new controllers shows that hydraulics theory can lead to improved controllers.
