Abstract

In this paper we investigate pressure regulation in large scale hydraulic networks with a multi-pump architecture. We propose distributed controllers that regulate the pressure drop at each end-user asymptotically towards desired set-points. We prove that the obtained closed-loop nonlinear system is locally asymptotically stable. In contrast to previous results, the proposed solution guarantees besides pressure regulation, that the pumps generate only positive pressures (inputs), required by many (centrifugal) pumps that are commonly used in hydraulic networks.
