Abstract

Developments in control of spatially-invariant processes are applied to an industrial problem of cross-directional profile control in web manufacturing. Approximating such processes in terms of a spatial frequency decomposition allows the extension of traditional concepts of loopshaping to the two-dimensional dynamical and spatial frequency domain. The approach is applied to a cross-directional paper weight process. The designed controller is implemented on a real industrial profile control system and demonstrates the performance predicted by the design.
