Abstract:
In the control of irrigation channels, there exists a tradeoff between
the local performance of regulating the water-level in each pool to a
given setpoint and rejecting offtake disturbances, on the one hand,
and decoupling between pools, on the other. Such a tradeoff is well
managed by a distributed control that inherits the interconnection
structure of the plant. Furthermore, to decrease the water-level
deviation from its setpoint in response to large offtakes, i.e. to
improve the transient response of the local closed-loop system, the
knowledge of the offtakes can be fed forward. This paper explores the
designing of a feedforward compensator to improve local control
performance while maintaining the good management of closed-loop
coupling between pools by distributed control.
