摘　　要：在阐述基于闭环控制的经编电子送经系统结构的基础上,文章主要研究了闭环送经控制系统在经编机启停过程中主轴转速的变化对经轴送经的影响,并对送经系统在启停过程中的经轴滞后于主轴运动和经纱张力变化进行了测试与分析。根据测得的经编机启停过程中经轴电机响应性能和送经张力变化规律,设计了一种经编机启停过程中的送经补偿方法,可显著提高经编机启停过程中送经张力的平稳性,进而改善经编产品品质。On a warp-knitting machine with closed-loop controlled electronic let-off system, the warp let-off is often impacted by the speed change of the main shaft during turning-on and turning-off the machine, since the movement of beam lags behind that of main shaft, causing tension change of the warp. By testing the response performance of beam motor and analyzing the law of warp tension change, a compensation method was developed, which can significantly improve the stability of let-off tension during start/stop of warp- knitting machine and consequently improve the quality of warp-knitted products.
