Abstract
For a string of pools with distant-downstream control, the internal time-delay
for water transport from upstream to downstream not only limits the local
control performance of regulating water-levels at setpoints and rejecting
offtake disturbances in each pool, but also impacts the global performance of
managing the water-level error propagation and attenuating the amplification of
control actions in the upstream direction. A distributed control scheme which
inherits the interconnection structure of the plant is studied. It is shown
that the decoupling terms in the controller helps to improve global closed-loop
performance by decreasing the low-frequency gain of the closed-loop coupling.
Moreover, they compensate for the influence of the time-delay by imposing extra
phase lead-lag compensation in the mid-frequency range on the closed-loop
coupling function.
