An open-loop control system for open-channel flows

摘要

A simple approach for computing an anticipatory open-loop (i.e., feedforward) control schedule to satisfy known water demand changes in open channels is proposed. The methodology assumes a sucession of steady-states and takes into account pool volume changes and delay times to generate a shedule of check flow rate changes. THe proposed procedure is a component of an automated control system currently under development for the Salt River Project in Arizona.
