基于RBF-PID的棉花变量施肥控制系统设计与试验
Design and Test of Variable Fertilization Control System for Cotton Based on RBF-PID
摘要
Abstract
With the continuous development and improvement of BeiDou satellite navigation technology and automatic con-trol technology in China,precision agriculture technology has gradually become the focus of research.In this paper,based on RBF-PID control and regulation algorithm,a PLC-based closed-loop control system for variable fertilization was de-signed,which can realize precise variable fertilization by using stepper motor-driven fertilizer rower to control N,P and K fertilizers individually according to BeiDou positioning information and fertilization prescriptions of different plots.Finally,the fertilization performance(fertilization accuracy and fertilization uniformity)of the control system was tested,the re-sults showed that the maximum relative error ε of the fertilizer discharge volume was 3.85%and the maximum uniformity coefficient of variation σ was 2.81%,which met the requirements of precision fertilization operation.关键词
