摘要:为了缩小水针最终停止位置与设定目标引纸位置的偏差问题,本研究基于水针移动控制系统,采用变速双死区方法,以控制低死区为例,针对合理选取控制低死区数值问题展开研究。通过现场多次实验测试数据,找出控制低死区数值合理范围,基于多项式拟合优化方法,建立水针位移与控制低死区数值的数学模型,求解出控制低死区数值,并进行生产应用验证。结果表明,选择控制低死区数值为30时,水针定位偏差最小,与设定位置偏差为6 mm,误差为-0.80%。
Abstract:In order to redurce the deviation between the final stop position and the set target threading position of the Trim Squirt, the problem of reasonable selection of control low dead zone value was studied using variable speed double dead zone method based on the trim squirt movement control system, taking control low dead zone as an example. Based on field test data and the polynomial fitting optimization method, the mathematical model of trim squirt displacement and control low dead zone value were established, finding out the reasonable ravge of control low dead zone value, and the control low dead zone value was selected, which was verified in production application. The results showed that when the control low dead zone value was 30, the trim squirt positioning deviation was the smallest, and the deviation from the set position was 6 mm, with the error of -0.80%.
