Abstract

Modern control systems tend to be based on computers and
therefore to operate by sending commands to structures at given intervals
(discrete time control system). Moreover, for almost all water management
control systems there are practical lower limits on the time interval between
structure adjustments and even between measurements. The water resource systems
that are being controlled are physical systems whose state changes
continuously. If we combine a continuously changing system and a discrete time
controller we get a hybrid system.We will show how the control action due to
the hydraulic behaviour of weirs and gates can help stabilize such a system.
