摘要: 以连续轧制过程中强耦合的板形板厚系统为研究对象,在对影响板形板厚控制的各种耦合因素进行系统分析的基础上,建立了加入油膜厚度影响的板厚和板形平直度耦合系统数学模型。在耦合关系上通过matlab仿真分析,可知改进模型板形与板厚的耦合关系明显。在此基础上利用自抗扰技术进行解耦设计,并以某厂五机架连轧机的实际参数采用计算机进行仿真,仿真结果表明设计的自抗扰解耦控制器可以有效消除板厚和板形平直度之间的耦合关系,解耦效果良好。

Abstract: In AFC-AGC strong coupling continuous rolling process as the research object,analysis various coupling factors of the system of the thickness control and strip flatness control and establishing the thickness and shape glancing flatness coupling model after adding the effects of oil film thickness.Based on the use of ADRC technique for decoupling design,and used computer to carry on the simulation to actual parameters of a factory of five tandem rolling mill,the simulation results show that the design of the disturbance decoupling controller can basically eliminate the coupling relationship between the thickness of plates and plate glancing flatness,and can get a good decoupling effect.

Key words: Shape glancing flatness,Thickness,Oil film thickness,Auto-disturbance rejection controller,Decoupling control
