Considering that the controller feedback gain and the observer gain are of additive norm-bounded variations,a design method of observer-based H-infinity output feedback controller for uncertain Delta operator systems is proposed in this paper.A sufficient condition of such controllers is presented in linear matrix inequality(LMI) forms.A numerical example is then given to illustrate the effectiveness of this method,that is,the obtained controller guarantees the closed-loop system asymptotically stable and the expected H-infinity performance even if the controller feedback gain and the observer gain are varied.
