Abstract
In the distant-downstream control of irrigation channels, the interactions
between pools and the internal time-delay for water to travel from upstream to
downstream, impose limitations on global performance, i.e. there exist
propagation of water level errors and amplification of flows over gates in the
upstream direction. This paper analyses these coupling properties for a string
of identical pools, both with identical feedback controllers and with
non-identical feedback controllers. The definition of string stability in terms
of bounded water level errors and bounded flows is given. It is shown that for
a string of infinite number of pools, string stability cannot be achieved by
decentralised distant-downstream feedback control. However, for a string of
finite number of pools, a better global performance can be achieved by
non-identical feedback controllers such that the closed-loop bandwidths of the
subsystems increase from downstream to upstream.
