Abstract
Adaptive control strategies have been developed for real-time management of irrigation. A closed-loop irrigation control system requires: (1) some combination of weather, soil, plant and irrigation data (2) control strategy to determine irrigation application and/or timing
(3) actuator hardware to adjust irrigation application.
'VARIwise' framework develops and simulates site-specific irrigation control strategies. VARIwise has been adapted to determine site-specific irrigation requirements of cotton.
A model predictive control strategy has been applied to surface irrigation by:
- calibrating a crop production model using the available weather, soil and plant data
- using the crop model to predict the irrigation timing and/or volume that produces the desired performance
- using the surface irrigation model SISCO to determine the irrigation flow rate and advance trajectory that best corresponds to the optimal irrigation distribution
