摘要: 为提高叶菜收获机智能化控制性能、降低劳动强度,设计了一套电动叶菜收获机自动对行控制系统。通过建立电动叶菜收获机转向机构数学模型和设计对行探测机构,采用PID和模糊控制技术建立了自动对行系统控制策略,并进行了仿真试验和田间试验。试验结果表明:在叶菜行发生偏移时,系统能及时调整行走轨迹,实现自动对行功能,提高了电动叶菜收获机的自动化水平。Abstract: In order to improve the intelligent control performance of the leaf vegetable harvester and reduce the labor intensity, a set of electric leaf vegetable harvester automatic alignment control system is developed.By establishing the mathematical model of the steering mechanism of the electric leaf vegetable harvester and designing the alignment detection mechanism, the control strategy of the automatic alignment system was established using PID and fuzzy control technology, and the simulation test and field test were carried out. The test results show that the control system can adjust the walking trajectory in time when the leaf vegetable row is shifting.It realizes the automatic alignment function and improves the automation level of the electric leaf vegetable harvester
