    • Dwell-time computation for stability of switched systems with time delays 

      Caliskan, S. Y.; Özbay, Hitay; Niculescu, S. I. (IET, 2013)
      The aim of this study is to find an improved dwell time that guarantees the stability of switched systems with heterogeneous constant time-delays. Piecewise Lyapunov-Krasovkii functionals are used for each candidate system ...
    • Finite time estimation through a continuous-discrete observer 

      Mazenc, F.; Ahmed, S.; Malisoff, M. (John Wiley and Sons, 2018)
      We study two broad classes of nonlinear time-varying continuous-time systems with outputs. For the first class, we build an observer in the case where a state dependent disturbance affects the linear approximation. When ...
    • On dwell time minimization for switched delay systems: Time-Scheduled Lyapunov Functions 

      Koru, A. T.; Delibaşı, A.; Özbay, Hitay (Elsevier B.V., 2016)
      In the present paper, dwell time stability conditions of the switched delay systems are derived using scheduled Lyapunov-Krasovskii functions. The derivative of the Lyapunov functions are guaranteed to be negative semidefinite ...
    • Stability analysis of switched systems using Lyapunov-Krasovskii functionals 

      Çalişkan, S.Y.; Özbay, Hitay; Niculescu, S.-I. (Elsevier, 2011)
      Piecewise Lyapunov-Razumikhin functions are previously used for obtaining a lower bound for the dwell time of the switched time delay systems under the assumption that each candidate system is delay dependently stable. In ...
    • Stability and robustness analysis for switched systems with time-varying delays 

      Mazenc, F.; Malisoff, M.; Özbay, Hitay (Society for Industrial and Applied Mathematics Publications, 2018)
      A new technique is presented for the stability and robustness analysis of nonlinear switched time-varying systems with uncertainties and time-varying delays. The delays are allowed to be discontinuous (but are required to ...
