Irrigation planning: An optimal control approach

AIP Conference Proceedings, 2013
We aim to plan the water usage in the irrigation of a given farmland keeping, at same time, the field cultivation in a good state of preservation. This problem is modeled and tackled as an optimal control problem: minimize the water flow (control) so that the extent water amount in the soil (trajectory) fulfills the cultivation water requirements.

Climate and Irrigation Control

2014
This chapter describes the climate and irrigation control problem inside a greenhouse and several control techniques widely used for such purposes, including illustrative results. As greenhouse crop production is influenced by inside climate, control strategies are important to maintain adequate conditions in spite of disturbances acting on the system.

Control of Irrigation Channels

IEEE Transactions on Control Systems Technology, 2008
Water losses in irrigation channels are large, but they can be substantially reduced by improving the control systems. The flows and water levels are controlled using overshot gates located along the channels, and in this paper we consider decentralized PI control and centralized multivariable LQ control of the flows and water levels.

REMOTE-CONTROLLED IRRIGATION SYSTEM

Water is essential for plant growth. Watering the plants is done by the irrigation process. Irrigation is the process of adding regulated amounts of water to land to support the growth of lawns, ornamental plants, and crops. The main objective of this system is that it doesn’t need human intervention.
