Abstract
We present a novel, simple and cost-effective strategy for control of
irrigation canals to aid water deliveries to the users through the canal. The
method enhances water deliveries through the canal by incorporating, alongside
local PI controllers maintaining water levels in each canal pool at some
predefined setpoints, a higher-layer centralized controller. The purpose of
that centralized controller is to coordinate the local controllers by modifying
the setpoints in individual pools. This speeds up the delivery process so that
water is available to users faster than when only local controllers are used.
Because the higher-layer centralized controller is invoked only when deliveries
are requested and in normal operating conditions the canal is maintained merely
by the local upstream PI controllers, the method is computationally efficient
and resilient to temporary communication failures. We use Time Instant
Optimization Model Predictive Control as the main control framework to design
the higher-layer centralized controller and present a simulation study to
illustrate the method proposed in this paper.
