dc.subject.otherThe H-infinity control problem has been extensively used to minimize the effects of the external disturbances
dc.subject.otherA gain-scheduled static state-feedback controller is designed to meet the performance requirements. A robust static gain-scheduled controller design for discrete-time polytopic LPV systems with a state delay has been formulated in a delay-independent matrix inequality framework
dc.subject.otherThe H-infinity control methods are used in control theory to synthesize controllers to achieve stabilization with guaranteed performance

local.description.resumoThis paper proposes new synthesis conditions to design H∞ static output-feedback controllers for discrete-time linear systems affected by time-varying parameters and time-varying delays. The design conditions are provided in terms of sufficient parameter-dependent linear matrix inequalities with a scalar parameter, being capable of synthesizing either robust or gain-scheduled controllers. The main motivations to deal with such problem are that many real-world plants can be modeled in terms of discrete-time linear parameter-varying (LPV) time-delay models and the lack of methods to deal with such systems considering an output-feedback based approach. The technique presented in this paper is quite generalist, allowing an arbitrary structure for the measured output matrix. Numerical examples are provided to illustrate the effectiveness of the synthesis conditions, tractable in terms of LMI relaxations, for robust or gain-scheduled H∞ output-feedback for LPV time-delayed systems.
