本文报告了一种用于设计空间分布反馈控制器的算法的开发和实现，该算法用于工业造纸机的交叉（CD）控制中包含的各种物理过程。这类过程模型的时空结构在使用二维频域进行分析和反馈控制器的二维回路成形设计中得到了充分利用。该算法构成了最近在商业产品中实现的软件工具的基础，并说明了其用于在两台不同的工业造纸机上调谐CD控制器的用途。第一个例子描述了该工具的使用，通过返回分布式控制器来稳定不稳定的闭环系统。第二个纸机示例暴露了一个性能不佳的控制器。随后控制器的调整导致了性能的显著提高。
This paper reports on the development and implementation of an algorithm for the design of spatially distributed feedback controllers for the wide variety of physical processes that are included in cross-directional (CD) control of industrial paper machines. The spatial and temporal structure of this class of process models is exploited in the use of the 2D frequency domain for analysis and 2D loop shaping design of feedback controllers. This algorithm forms the basis of a software tool that has recently been implemented in a commercial product and its use is illustrated for tuning CD controllers on two different industrial paper machines. The first example describes the use of the tool in stabilizing an unstable closed-loop system by retuning the distributed controller. The second paper machine example exposes an underperforming controller. Subsequent retuning of the controller resulted in a dramatic performance improvement.
