本文应用自动控制理论,重点从液压的角度分析研究了一个实验用拖拉机电液力控制系统的动态性能,提出了反映系统动态性能的数学模型和评价指标,并将理论分析的结论与试验结果进行了对比,取得了比较一致的结果。本文虽然是对一个具体系统的分析,但所用的分析方法可以用于研究其他类似的拖拉机牵引阻力控制系统的动态性能。
In this paper, the automatic control theory is applied. The dynamic performance of an experimental tractor electro-hydraulic control system is analyzed emphatically from the perspective of hydraulic pressure. A mathematical model and evaluation index reflecting the dynamic performance of the system are put forward. The conclusions of theoretical analysis and experimental results In contrast, achieved a more consistent results. Although this paper analyzes a specific system, the analysis method used can be used to study the dynamic performance of other similar tractor traction resistance control systems.
