摘　　要：本文把单机架冷轧机作为一个双变量系统来处理,分析了该系统的输出最(前张力和出口厚度)之间的耦合关系;通过对压力方程、力矩方程、前滑方程等在某种轧制条件下进行线性化,建立了该系统被控对象的数学模型。本文旨在实现前张力和出口厚度的解耦控制,为此,基于多变量系统解耦控制理论和自适应控制方法,本文提出了一种单机架冷轧机多变帚系统增裢调度解耦控制方法,并给出了其应用于轧机系统的仿真结果。In this paper,a single stand cold rolling mill is processed as a dual-variable system,inter-action between outputs (forward tension and exiting thickness) of the system is analyzed.Ma-thematical model of the controlled object in the system is built by means of linearzing pressureequation,torque equation and forward slip equation under some rolling conditions.The papertends to realize the decoupling control of forward tension and exiting thickness,so a gain adju-stment decoupling control method of multivariable system for single stand cold rolling mill israised based on multivariable system decoupling control theory and adaptive control method,and the results obtained from simulating application of this control method to a rolling mill arealso given.
