摘　　要：化纤生产中,高速卷绕头控制的关键是提高卷绕速度控制的精度。本文针对卷绕系统具有复杂时变速度给定、跳变负载干扰、参数不确定和要求恒线速度的特点,分析了卷绕叠丝的原因,利用先进的致密精密卷绕方式,大大改善了卷转的成形质量。在线速度控制问题上,比较了PI控制器和ADRC两种控制方式,结果表明ADRC控制的效果明显好于PI控制器,速度控制满足系统要求。In fibre manufacture of chemical plants, it requires good quality to the high-speed winder.The sticking point to design winding drives is to improve the precision of the speed. The wind control system has the characteristic of perplexing and time variational speed demand, pulsatile and variational loads to disturb, uncertain parameter and request of invariableness for line speed. Based on winding characteristics, we analyze the probability of forming cobweb. It improves the winding formation by introducing the advanced mathod - CPW （compact precision winding）. Considering the need for constant velocity, we compared PI controller and ADRC controller. According to the practical curve, ADRC controller is excelled more. The design tallied with demands of the system,ADRC is regarded as an important technique to resolve the problems.
