Design of Farm Irrigation Control System Based on the Composite Controller

Abstract

Farmland irrigation is an essential foundation for good crop growth, while traditional farmland irrigation techniques cannot fully consider the impact of factors such as natural precipitation and crop transpiration on crop growth, which can, to a certain extent, result in poor irrigation decisions and a complex farmland environment that cannot be monitored promptly, thereby reducing farmland production efficiency. This study designs a farmland irrigation control system based on a composite controller. Firstly, an irrigation control method is proposed to establish a prediction model for future rainfall and crop transpiration using historical meteorological data. The composite controller is designed based on the prediction model to realize an irrigation control operation with an irrigation value as the control quantity, a water and fertilizer machine, and a solenoid valve as the actuators. Secondly, an intelligent irrigation control cloud platform based on Java language is designed to monitor farm information and irrigation operation records in real-time to facilitate visual management. Finally, the prediction accuracy is high, based on the prediction model results, which can provide a specific reference basis. The superiority of the proposed controller is verified by simulation using MATLAB/Simulink. The results show that the proposed controller can be well suited for nonlinear control systems and has good control performance while ensuring high tracking accuracy, strong robustness, and fast convergence.

Installation and Adjustment of a Hydraulic Evapotranspiration Multisensor Prototype

“…Along this line, other authors have indicated that the water requirements for several crops can be sufficiently modeled for the considered climate based on virtual sensors and fuzzy logic control systems [7,8]. Li et al [9] proposed a composite irrigation controller that considers predictive algorithms, crop coefficients, fuzzy algorithms, and sliding mode control methods for maize irrigation scheduling.…”

“…Their simplicity and high degree of adaptation at the farm level, which are characteristics of the evaporation pan, seem to be the primary reason for the pan's expansion among producers. The work of Thomson and Fisher (2006) [9], who designed an evaporimeter based on a washtub for easy cotton irrigation scheduling, is relevant. Similarly, other researchers have proposed activating a drip irrigation system based on a water level sensing system in a mini-pan [18].…”

Reliable Multi-Path Communication for IoT Based Solar Automated Monitoring as Motivation Towards Multi-Farming Hydroponic

“…Despite the availability of real-time control of farm equipment through automated actuation devices, such as feeders, seed drills, valve-controlled irrigation systems, etc., in the market, there has been limited progress in the development of wireless technologies for transferring sensor data wirelessly from crop fields to remote servers [6,21]. Besides that, agriculture has become more complex, and farmers cannot rely solely on traditional farming methods to improve their yields and profits [7].…”
