Observer-based H-infinity controller design for state delayed linear systems

Abstract

We present two alternative observer-based H-infinity control design methods for linear dynamic systems with delay in the state. Based on the Riccati-equation approach, we design observer-based feedback control laws that guarantee the asymptotic stability if the closed-loop control system and reduce the effect of the disturbance input on the controlled output to a prescribed level.
