Non-fragile Dynamic Output Feedback H ∞ Control for Continuous-Time Systems with Controller Coefficient Sensitivity Consideration
This paper presents a study on the problem of non-fragile dynamic output feedback. .∞ controller design for linear continuous-time systems with controller coefficient sensitivity consideration. The controller to be designed is assumed to be with multiplicative gain variations, which are resulted from controller implementations. A notion of structured vertex separator is employed to approach this problem, and exploited to develop sufficient conditions for the non-fragile H∞ controller design via a two-step procedure. The resulting designs guarantee that the closed-loop system is asymptotically stable and the H∞ performance from the disturbance to the regulated output is less than a prescribed level. A numerical example is given to illustrate the design methods.
