Wirelessly Controlled Irrigation System

Iraqi Journal for Electrical and Electronic Engineering, 2014
In the city of Basrah, there is an urgent need to use the water for irrigation process more efficiently for many reasons: one of them, the high temperature in long summer season and the other is the lack of sources fresh water sources. In this work, a smart irrigation system based wireless sensor networks (WSNs) is implemented.

Model predictive control for precision irrigation of a Quinoa crop

Open Chemistry, 2022
Traditional High Andean agriculture is rainfed, and irrigation is commonly carried out in an open loop, that is, without measuring variables such as soil moisture content or plant development to define water consumption.

New offset-free method for model predictive control of open channels [PDF]

, 2015
Irrigation or drainage canals can be controlled by model predictive control (MPC). Applying MPC with an internal model in the presence of unknown disturbances in some cases can lead to steady state offset.

Steering of fogging: control of humidity: temperature or transpiration [PDF]

, 2008
Fogging systems are increasingly used to cool greenhouses and prevent water stress. More recently, fogging systems are applied also in relatively low radiation environments (such as The Netherlands), for a better control of product quality than ...
