Abstract
We consider systems where information about model accuracy iscontained in a model error model. The validity of such a model istypically restricted to input signals that are limited in amplitude.It is then natural to require the same amplitude restriction whendesigning controllers. The resulting implications for controllerdesign are investigated using non-linear H-infinity techniques.
