Non-Fragile Dynamic Output Feedback Control with Norm-Bounded Gain Uncertainty

4.1    Introduction

In Chapter 3, based on algebraic Riccati inequality techniques, the problem of non-fragile guaranteed cost control for discrete-time linear systems under state feedback controller gain uncertainties was investigated. However, in many systems, all of the system states are often not fully available, not measurable, or too expensive to measure, in particular for the case that only the system output is available and therefore this condition limits the practical applicability of state-feedback control schemes [14, 117]. Correspondingly, dynamic output feedback controllers are desired and every important both in theories and applications, and also ...
