重卷机组速度和张力的控制策略及应用

The application and control strategy of the speed and tension of the heavy volume unit

简要介绍了重卷机组的工艺流程和控制要求,阐述了重卷机组的速度控制和张力控制策略,重点分析了卷取机的速度控制原理和开卷机在基速以上以及基速以下的张力控制原理,并给出了卷取机速度闭环控制的实际方法,以及采用最大力矩控制方式实现开卷机张力开环控制的实际方法。同时给出了动态计算开卷机和卷取机上实时卷径的方法。

Briefly introduce the process flow and the control requires for the recoil line, and introduces the strategy of the speed control and tension control for the recoil line. The principles of the speed control for the tension reel and the tension control of over and below base speed for the payoff reel are analyzed in detail, the practice methods of the speed close loop control for the tension reel and the maximum tension open loop control for the payoff reel are introduce, and the practice method which dynamic calculate the diameter of coiler in payoff reel and tension reel is introduced at the same time.
