摘要
为有效应对造纸机水针移动惯性所造成的定位偏差,确保水针精准且快速移动,以拟合优化方法构建了造纸机水针移动控制数学模型.采取变速双控制中性区方法,以反复测试寻找控制中性区数值的合理范围,并针对性建立水针移动与中性区数值的数学模型,以求解控制中性区数值.实际应用验证结果表明,变速双控制中性区方法的引进使造纸机水针移动曲线变化趋向于平缓,且终止位置与设定位置误差控制于0.79%,精确度非常高;相比传统变速单控制中性区方法,水针移动响应时间缩短了 25s.
Abstract
To effectively address the positioning deviation caused by the inertia of paper machine water needle movement and ensure accurate and rapid movement of the water needle,this paper constructs a mathematical model for paper machine water needle movement control using a fitting optimization method.Adopting the variable speed dual control neutral zone method,repeatedly testing to find a reasonable range of control neutral zone values,and establishing a targeted mathematical model for water needle movement and neutral zone values to solve the control neutral zone values.The practical application verification results show that the introduction of the variable speed dual control neutral zone method makes the movement curve of the paper machine water needle tend to change smoothly,and the error between the end position and the set position is controlled within 0.75%,with very high accuracy;compared to the traditional variable speed single control neutral zone method,the water needle movement response time is shortened by 25 seconds.
