Robust delay-free observer-based controller design for uncertain neutral time delay systems

Parlakçi, M.N.A.2024-07-182024-07-1820060137-1223https://hdl.handle.net/11411/6713This paper deals with the problem of designing robust delay-free observer-based controller for a class of neutral time delay systems with parameter uncertainties. A new linear matrix inequality approach is developed for designing the robust delay-free state-feedback controller that can simultaneously guarantee the global asymptotical stability of the estimation process and closed-loop system independently of the time delay. Employing Lyapunov stability method and quadratic stability theory, new delay-independent stability criteria are obtained in the form of linear matrix inequalities which can be easily solved by well-known interior-point algorithms. Two numerical examples are introduced to demonstrate the effectiveness of the proposed method through simulation studies.eninfo:eu-repo/semantics/closedAccessAlgorithmsAsymptotic AnalysisControl EquipmentFeedback ControlLyapunov MethodsRobust ControlStability CriteriaDelay-İndependent Stability CriteriaInterior-Point AlgorithmsUncertain Neutral Time Delay SystemsUncertain SystemsRobust delay-free observer-based controller design for uncertain neutral time delay systemsArticle2-s2.0-38549091551441N/A2732
