The key to control flying gage change(FGC) on a tandem cold mill is to deal with the intercoupling between the process variables,such as thickness,stress and so on.

冷连轧动态规格变换过程实现控制主要困难在于冷轧过程中厚度、张控变之间耦合作用。

A continuous reheating industrial furnace is large inertia,pure delay,multi-variables,time-vary-ing,intercoupling complicated controlled plant,and has many uncertain factors.

连续式加热炉是个典型具有大惯性、纯滞后、多变、时变并且耦合复杂控对象,而且有许多不确定因素。
