闸门控制系统油缸行程偏差修正模型研究

Research on Cylinder Stroke Deviation Correction Model of Gate Control System

针对闸门控制系统中油缸行程随开度变化而造成测量偏差的问题,本文通过行程测量装置研究了闸门开度与偏差数据的关系,并根据其非线性关系进行多项式拟合,建立行程偏差修正模型,对闸门的行程实现精确补偿。实验结果表明,经过偏差修正后,闸门启动和停止均正常运行,修正前的最大相对偏差由7.84%减小到修正后的最大相对偏差0.61%,且随着开度的变化,油缸行程偏差无明显波动,提高了闸门安全运行的可靠性。

In this paper,for resolving the problem of the measurement deviation caused by the change of oil cylinder stroke with the opening in the gate control system,the accurate compensation for the gate stroke is realized,which is based on the relationship between the gate opening and the deviation data through the stroke measurement device,the polynomial fitting according to its nonlinear relationship,and the stroke error correction model.The experimental results show that after the deviation correction,the gate starts and stops normally,and the maximum relative deviation is reduced from 7.84% to 0.61%.In addition,the cylinder stroke deviation has no obvious fluctuation with the change of opening,which improves the reliability of safe operation of the gate.
