Two-dimensional control systems: Learning from implementations

摘要

The design of sensing and control systems for two- dimensional industrial processes such as paper making, plastic film extrusion and metal rolling, has drawn extensively upon concepts from two-dimensional signal processing and image processing. The performance of two-dimensional control systems is discussed in terms of spatial and dynamic bandwidths and is illustrated by ex- amples from the control of cross-directional variations on a plastic film extrusion line.
