'l'his paper presents a digital control scheme for water level rc:gulat.ion in canals. The scheme considers a prototyl)e canal composed by a series of pools connected with activ(a gatrs. A control system is designed for each pool with the objective of manipulating the upstream gate in order to drive and maintain the downstream level at dehirctl valuw. I,Zach control system is composed by two cx)nt.rollcrs: OIIP implements a discrete time predictive cont.rol law that gives the desired discharge through the gat.e as to cnsurc the downtream desired level; another on? implements a local control law t,o move the gate to ac-hic,vc the desired discharge. The paper presents the formulation of the global control scheme and shows results from simulations to illustrate and discuss the perforniancc: in diffexnt operat,ion scenarios.
