Non-fragile Dynamic Output Feedback H_∞ Control for Discrete-Time Systems with FWL Consideration

摘要

The non-fragile dynamic output feedback H_∞ controller design problem is investigated. The controller to be designed is assumed to be with additive gain variations. A two-step procedure is proposed to develop sufficient conditions for the non-fragile H_∞ controller design by employing the structured vertex separator. A comparison between the proposed and the existing controller design methods is provided, and a numerical example is carried out to support the theoretical findings.
