摘　　要：为进一步提高并条机自调匀整技术,在分析纺织并条机自调匀整控制系统优劣的基础上,提出一种新的双开环控制系统,给出了新型控制系统的数学模型,详细分析了其数学原理,阐述了双开环自调匀整控制系统的理论基础。通过比较开环、闭环和混合环控制系统认为,该控制系统能够缩短盲区,消除死区,并能2次匀整条干。通过性能分析得出,双开环控制系统能够获得更好的匀整效果。To further enhance the autoleveling technology of drawing frame,a new type of dual open-loop control system was issued based on the analysis of the quality of the current autoleveling control system of drawing frame.This paper presented a mathematical model of the new control system,analyzed its mathematical theory,and elucidated the theoretical basis of dual open-loop autoleveling control system.By comparing the open-loop control system,closed-loop control system and mixed-loop control system,the paper drew a conclusion that the new control system could shorten the blind area,eliminate the dead area,and autolevel cotton sliver twice.Through performance analysis,the dual open-loop control system could achieve a better effect.
