Abstract | This work considers recent theoretical results for dynamical systems distributed in one spatial dimension. An application is presented for an industrial papermaking control system that had been experiencing frequent closed-loop instability problems. Two-dimensional frequency domain analysis uncovered a very small robust stability margin in the region corresponding to qualitative observations of the instability. A two-dimensional loop shaping technique was then used to redesign the feedback controller to obtain a closed-loop system with an acceptable stability margin. The system was observed to remain stable over the course of four days of closed-loop operation. |
