Abstract :
In this paper, recent developments in control of spatially-invariant processes are applied to an industrial problem of cross-directional profile control in papermaking. The process is approximated in terms of a spatial frequency decomposition which allows the extension of traditional techniques of loopshaping to the two-dimensional dynamical and spatial frequency domain. The designed controller is implemented on a real industrial profile control system and demonstrates the performance predicted by the design
