模型参考自适应在轧机两侧压下特性一致控制中的应用

The Application of Model Reference Adaptive Control to Keeping Identical Pressing Character of Both Sides of Rolling Mill

冷轧机两侧液压压下系统的不一致性导致了带材横向厚差分布不均匀 ,直接影响带材的板形质量 .针对此问题 ,本文应用模型参考自适应方法 ,提出了两侧压下系统共用同一参考模型的系统结构 ,对系统进行了综合和控制 ,收到了良好的实际应用效果 .

The vary character of both sides of cold rolling mill hydraulic pressing system leads to an unequal horizontal thickness difference distribution of strip which affects strip shape directly.In order to solve this problem,we apply a kind of MRAC method which makes both sides of pressing system share a single model.By synthesizing and controlling the system,we get a very good actual effect.
