摘 要:采用前馈预控、反馈监控的复合控制实现甘辊可逆冷轧机的AGC(即厚度自动控制);并在新的厚控模型基础上提出改进措施,克服了经典厚控方法在动态过程和系统在线参数辨识中精度差、计算量大等局限。
Abstract: This paper describes a complex control scheme combined with feed forward precontroland feedback monitor control to realize the automatic Control of sendzimir reversible cold-mill. Based on a gauge control model,it also gives Some improved ways to overcome the poorprecision limits in the dynamic process and to avoid too much computation in the on-line i-dentification of the traditional gauge control method.
