A pressurized headbox with significant uncertainty in dynamics is considered and assumed to be represented by a set of multiple finite-dimensional linear time-invariant models. The principal purpose is to design a fixed robust controller in a unit output feedback configuration such that the resulting feedback system simultaneously satisfies the given performance objectives for all models in the set. A new approach is developed in frequency domain and its effectiveness is illustrated by simulations.
