Overview

Simulation study demonstrates improved regulation and precision in variable fertilization systems, indicating reduced agricultural resource waste.

Key Points

To design and evaluate an optimized proportional-integral-derivative (PID) control algorithm for variable fertilization systems to enhance dosing accuracy and regulation stability.
Constructed a mathematical model of a variable fertilizer application system using the MATLAB/Simulink platform.
Optimized fuzzy PID controller gain parameters using a hybrid bacterial foraging-particle swarm optimization algorithm.
Benchmarked control performance and fertilizer dosing accuracy across varying pressure levels against standard PID, fuzzy PID, and particle swarm-optimized PID controllers.
The hybrid algorithm achieved superior regulation performance, smaller overshoot, enhanced stability, and faster steady-state rise time relative to conventional PID, fuzzy PID, and PSO-PID methods.
Experimental testing under multiple operational pressures demonstrated high fertilizer application accuracy, significantly reducing resource waste during crop irrigation.
