Abstract
A decntralized conrol method for water distribution networks is proposed and evaluated. In order to realize the decentralized control, this paper solves the following two problems. The first problem is how to decompose the water distribution networks. The second is selection of the control law to be applied to each decompose subsystem.
For the first problem, this paper proposes overlapping decentralized control structure based on the sensitivity matrix. It is shown that convergence rate of the overlapping decomposition structure is superior to that of completely separate decomposition. For the second problem, an adaptive control law is derived which assumes linear input-output relationship with unknown parameters. The proposed method is evaluated by simulation study for an actual large scale distribution network. It is obtained that the method is superior to a conventional completly separated decentralized one in terms of control performance. It is also mentioned the method attains highly reliable control configuration.
