| 铝板带材轧制生产过程是一个复杂的非线性控制对象, 其中自动板形控制(AFC)和自动板厚控制(AGC)又是一个相互耦合的复杂系统, 其参数在运行过程中会随时发生变化. 针对铝板带材轧制的特点提出了将自适应控制与板形板厚控制系统数学模型相结合, 自动调整解耦网络和控制器的参数. 现场实际数据的仿真结果表明, 该方法的应用消除了参数变化产生的影响, 使板形板厚控制系统具有良好的自适应跟随参数变化和抗干扰性能, 解耦控制效果良好, 提高了板形板厚的控制精度. |
| 英文摘要 |
| The rolling process of aluminum plates and strips is a very complicated nonlinear control object; and the automatic flatness control(AFC) and the automatic gauge control(AGC) are two coupling complex systems with varying
parameters in operation. Based on the characteristics of the aluminum plate and strip in rolling, we propose an adaptive control method which combines the mathematical models of AFC and AGC to automatically adjust the parameters in
the decoupling network and the controllers. The simulation of field data indicates that this method avoids the effects of parameter variations by letting AFC and AGC to adaptively track the parameters variations for reducing disturbances. It ensures a good performance in decoupling，and improves the precision of flatness and gauge control. |
