Adaptive observer designs for friction estimation in position control of simple mechanical systems with time delay
(Bilkent University, 2021-09)Friction force/torque is a well known natural effect that can cause performance degradation or even instability in mechanical systems, although it sometimes can be disregarded in closed loop feedback design phase. Hence, ... -
Dwell time optimization in switching control of parameter varying time delay systems
(IEEE, 2011)It has been shown that parameter varying systems with time delays can be robustly stabilized by switching control, provided that the plant's parameter varies slowly enough such that the dwell time conditions of the switched ... -
Dwell-time computation for stability of switched systems with time delays
(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 ... -
On dwell time minimization for switched delay systems: Time-Scheduled Lyapunov Functions
(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 ... -
On switching H∞ controllers for a class of linear parameter varying systems
(Elsevier BV, 2007)We consider switching H∞ controllers for a class of linear parameter varying (LPV) systems scheduled along a measurable parameter trajectory. The candidate controllers are selected from a given controller set according to ... -
Stability analysis of switched systems using Lyapunov-Krasovskii functionals
(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 analysis of switched time-delay systems
(IEEE, 2008-12)This paper addresses the asymptotic stability of switched time delay systems with heterogenous time invariant time delays. Piecewise Lyapunov-Razumikhin functions are introduced for the switching candidate systems to ... -
Switched PD-like controllers for first order unstable systems with time delay
(IFAC, 2009)A new method is proposed for the design of PD-like (first order stable) controllers for switched first order unstable systems with time delays. For this purpose, a dwell-time based stability condition of Yan and Özbay ... -
A switching control approach to stabilization of parameter varying time delay systems
(IEEE, 2009)Robust stabilization problem is considered for time varying time delay systems, where the system parameters are scheduled along a measurable signal trajectory. A switching control approach is proposed for a class of parameter ...
