Decentralized H-infinity control of systems with information structure constraints

Abstract

The paper deals with a class of continuous-time statedelayed uncertain systems considering H-infinity control. The main objective is to design static output feedback controllers satisfying three requirements simultaneously: asymptotic stability for the closed-loop system, a minimum effect of the disturbance input on the controlled output, and the obtention of a gain matrix having an arbitrarily preassigned zerononzero structure. To solve this problem, a linear matrix inequality (LMI) delay-independent approach is derived. A numerical example illustrates the effectiveness of the proposed method
