Dwell time-based stabilisation of switched delay systems using free-weighting matrices
Koru, A. T.; Delibaşı, A.; Özbay, Hitay (Taylor and Francis, 2018)In this paper, we present a quasi-convex optimisation method to minimise an upper bound of the dwell time for stability of switched delay systems. Piecewise Lyapunov-Krasovskii functionals are introduced and the upper bound ... -
Dwell time-based stabilisation of switched linear delay systems using clock-dependent Lyapunov-Krasovskii functionals
Koru, A. T.; Delibaşı, A.; Özbay, Hitay (Taylor and Francis, 2018)Dwell time stability conditions of the switched delay systems are derived using multiple clock-dependent Lyapunov-Krasovskii functionals. The corresponding conditions are approximated by both using piecewise linear functions ... -
Dwell time-based stabilisation of switched linear delay systems using clock-dependent Lyapunov–Krasovskii functionals
Koru, A. T.; Delibaşı, A.; Özbay, Hitay (Taylor and Francis, 2020)Dwell time stability conditions of the switched delay systems are derived using multiple clock-dependent Lyapunov–Krasovskii functionals. The corresponding conditions are approximated by both using piecewise linear functions ... -
Low-order controller design for haptic systems under delayed feedback
Liacu, B.; Koru, A. T.; Özbay, Hitay; Niculescu, S. -I.; Andriot, C. (2012)In this paper, we consider PD controller design for haptic systems under delayed feedback. More precisely, we present a complete stability analysis of a haptic system where local dynamics are described by some second-order ... -
On dwell time minimization for switched delay systems: free-weighting matrices method
Koru, A. T.; Delibaşı, A.; Özbay, Hitay (IEEE, 2014)In this paper, we present a quasi-convex minimization method to calculate an upper bound of dwell-time for stability of switched delay systems. Piecewise Lyapunov-Krasovskii functionals are introduced and the upper bound ... -
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 ... -
Optimizing low-order controllers for haptic systems under delayed feedback
Liacu, B.; Koru, A. T.; Özbay, Hitay; Niculescu, S. -I.; Andriot, C. (Elsevier, 2013-05)In this paper, a PD controller design for haptic systems under delayed feedback is considered. More precisely, a complete stability analysis of a haptic system where local dynamics are described by some second-order ...
