Abstract: An automated irrigation system includes a movable structure that has nozzles for spraying water on aimed area of ground. A controller selects a nozzle and determines a location in an unwatered area to be sprayed after the movable structure has moved forward. A predictive model that takes into account look-ahead sensor data for the location before watering and prior look-behind sensor data from a last time the location was watered is used to generate a watering prescription for the nozzle. After watering, the controller determines an error in detected moisture of the location according to updated look-behind sensor data and updates the predictive model if the error exceeds a threshold. When generating watering prescriptions for multiple nozzles, the controller normalizes their duty cycles by adjusting the speed of the movable structure and further customizes their nozzle control signals to ensure the nozzles do not turn off at same time.
