本文建立了TWC（张力宽度控制系统）宽度控制系统控制在精轧区由不同原因引起的宽度偏差。调节的机理是通过改变活套电机电流和角度来调节精轧机架间的张力。针对由不同的原因引起的宽度偏差，本文给出了相应的控制策略和方法以及控制模型。该控制系统由四个控制模型组成，分别控制由粗轧出口引起的宽度偏差、材料硬度引起的宽度偏差、周期性宽度误差和随机性宽度误差。该控制系统投入使用后，带钢宽度的均一性得到明显改善。

The TWC control system was designed to control width variations introduced by different reasons in finishing train. The adjustment mechanism is inter-stand tension modifications through changing looper motor currents and angles . According to the width deviations caused by different reasons, control strategy and methodology and control model was given. The control system is composed of four model, which control width deviations due to the width deviations at the exit of the roughing train, width errors due to material hardness variations, periodic width errors and random width errors. With the TWC system, a better uniformity in the width has been improved a lot.
