Abstract :
In this paper, we consider the problem of designing Hinfin static output feedback controller for systems with delayed state, delayed input and sensor failure. Two sufficient conditions for the existence of Hinfin output feedback controllers are presented. Furthermore, by using variable transformation and Schur complement, the obtained result can be rewritten as a matrix inequality representation. Through a set of solution of matrix inequalities, we can obtain the static output controller that can make the closed-loop system asymptotically stable, and its Hinfin norm being less than the given bound. Finally, an example is presented to show that the effectiveness of the method.
