Abstract

Optimal controller design for spatially distributed dynamical systems, as recently shown, is greatly simplified when spatially invariant models axe used. However the true spatial boundary conditions of many practical systems, including paper machine cross-directional processes, disrupt the spatial invariance and potentially destabilize the control system if not taken into account. This paper considers design of stability-preserving spatial boundary conditions for paper machine cross-directional controllers originally computed for idealized spatially invariant processes.
