Abstract

This study proposes an improved honey badger algorithm (IHBA) and a linear active disturbance rejection controller (LADRC) for the electric red bean precision seeder control system to solve high sowing missing rates and uneven sowing in high-density red bean precision sowing. The research details the design process of the intelligent control system, the improvement of the honey badger algorithm, and the intelligent adjustment method for key parameters of the LADRC controller. Simulation experiments show that the IHBA-LADRC based control system has no overshoot, short adjustment time, minimal steady-state error, no oscillation, and strong anti-interference ability. The system achieves an adjustment time of 0.79 seconds, almost zero static error, and an interference recovery time of 0.22 seconds. Bench tests indicate that compared to traditional PID electronic control sowing, the IHBA-LADRC system improves the pass index by 1.32 percentage points, reduces the multiple index by 0.49 percentage points, and lowers the missed sowing index by 0.76 percentage points. The overall variation coefficient decreases by 6.30 percentage points, and the variation coefficient of qualified plant spacing drops by 5.43 percentage points.This system reduces the discrepancy between the actual and theoretical plant spacing of red beans, ensuring uniformity and quantity consistency of red bean planting between ridges, and facilitates subsequent field management.

本研究针对高密度红豆精播中的高漏播率和播种不均匀问题，提出了一种改进的蜜獾算法（IHBA）和线性自抗扰控制器（LADRC）用于电动红豆精播机控制系统。该研究详细阐述了智能控制系统的设计、蜜獾算法的改进以及LADRC关键参数的智能调整方法。模拟实验表明，基于IHBA-LADRC的控制系统具有无超调、调整时间短、稳态误差小、无振荡和抗干扰能力强的特点。该系统实现了0.79秒的调整时间，几乎无静态误差和0.22秒的干扰恢复时间。台架测试结果表明，与传统的PID电子控制播种相比，IHBA-LADRC系统使格指数整体提高了1.32个百分点，重播指数降低了0.49个百分点，漏播指数降低了0.76个百分点。总体变异系数降低了6.30个百分点，合格株距的变异系数降低了5.43个百分点。该系统减小了实际株距与理论株距之间的差异，确保了不同垄间红豆种植的均匀性和数量一致性，并简化了后续的田间管理。
