浆纱机织轴的恒张力控制

Constant tension control on weaving- reel of starching- yarn machine

介绍一种浆纱机织轴恒张力的控制方法.系统采用间接法进行恒张力控制,利用现代传动设备变频器和工业控制计算机组成电气恒张力控制系统.该系统采用智能PID数字控制,具有动、静态性能好、可靠性高和抗干扰能力强等特点,可以替代传统的机械恒张力控制系统.

This article introduces a method on constant tension control on weaving-reel of starching - yarn machine. The system mainly takes an indirect method to control the constant tension which consists of a modern transmission frequency transformer and an industrial control computer. It adopts intelligent PID digital control which has some advantages of good functions both on dynamic state and static state, high reliability and strong and-interference, thus making it to be able to replace the traditional mechanical constant tension control system.
