    摘要:

    自動導(dǎo)航拖拉機在側(cè)偏側(cè)滑等工況下路徑跟蹤誤差大,、糾偏易超調(diào)且調(diào)節(jié)時間長,。為解決拖拉機側(cè)偏側(cè)滑工況快速糾偏問題,提出了一種基于驅(qū)動輪橫向控制補償策略的改進純追蹤路徑跟蹤控制方法。通過構(gòu)建拖拉機的坡面?zhèn)然P?結(jié)合二輪車運動學(xué)模型,提出了純追蹤算法的橫向控制補償策略,對經(jīng)典純追蹤算法進行改進,實現(xiàn)自動駕駛拖拉機精確橫向補償控制,。為驗證本文橫向側(cè)偏補償改進純追蹤路徑跟蹤算法性能,進行CarSim/Simulink聯(lián)合仿真,緩坡試驗結(jié)果表明,改進后的算法在10°斜坡上的控制精度相比經(jīng)典算法提升了73.6%;持續(xù)側(cè)滑仿真,經(jīng)典算法無法脫困,而改進算法在3.9s內(nèi)完成脫困,橫向偏差收斂至0.01m以內(nèi),超調(diào)量為0.14m,。此外本文還在田間試驗中驗證了改進算法的有效性,在相同試驗條件下,進行了3次重復(fù)試驗,結(jié)果表明拖拉機在所有試驗中均成功脫困,試驗表明平均脫困時間為7.03s,平均最大超調(diào)量為0.054m。試驗結(jié)果表明,本文橫向控制補償策略顯著提升了自動導(dǎo)航拖拉機在復(fù)雜工況下的控制精度和穩(wěn)定性,。

    Abstract:

    Automatic navigation tractors experience large path tracking errors, easy overshoot in correction, and long adjustment times under conditions such as lateral deviation and sideslip. Aiming to address the problem of fast correction for lateral deviation and sideslip in tractors, an improved pure pursuit path tracking control method was proposed, based on a lateral control compensation strategy for the drive wheels. By constructing a tractor sideslip model on a slope and combining it with a two-wheel vehicle kinematic model, a lateral control compensation strategy was introduced to improve the classic pure pursuit algorithm, achieving precise lateral compensation control for autonomous tractors. To validate the performance of the proposed lateral deviation compensation improved pure pursuit path tracking algorithm, CarSim/ Simulink co-simulation was designed. The results of the sloped test showed that the improved algorithm enhanced control accuracy by 73.6% on a 10°slope compared with that of the classic algorithm. In the continuous sideslip simulation, the classic algorithm failed to escape, whereas the improved algorithm completed escape within 3.9 s, with lateral deviation converging to within 0.01 m and an overshoot of 0.14 m. Field tests were conducted to verify the effectiveness of the improved algorithm, with multiple trials showing an average escape time of 7.03 s and a maximum overshoot of 0.054 m. The test results demonstrated that the proposed lateral control compensation strategy significantly improved the control accuracy and stability of autonomous navigation tractors in complex working conditions.
