Distributed output feedback control of decomposable LPV systems with delay and switching topology: application to consensus problem in multi-agent systems
Zakwan, Muhammad; Ahmed, Saeed (Taylor & Francis, 2020-01-08)This paper presents distributed output feedback control of a class of distributed linear parameter varying systems with switching topology and parameter varying time delay. To formulate the synthesis conditions for the ... -
Distributed output feedback control of decomposable lpv systems with delay: application to multi-agent nonholonomic systems
Zakwan, Muhammad; Ahmed, Saeed (IEEE, 2019)This paper presents distributed output feedback control of a class of distributed linear parameter varying systems with a parameter-dependent time-varying delay. A delaydependent bounded-real lemma approach, based on ... -
Dynamic output feedback stabilization of switched linear systems with delay via a trajectory based approach
Ahmed, Saeed; Mazenc, F.; Özbay, Hitay (Elsevier, 2018)A new technique is proposed to construct observers and to achieve output feedback stabilization of a class of continuous-time switched linear systems with a time-varying delay in the output. The delay is a piecewise ... -
Finite time estimation for time-varying systems with delay in the measurements
Ahmed, Saeed; Malisoff, M.; Mazenc, F. (Elsevier, 2019)We build finite time observers for time-varying nonlinear systems with delays in the outputs, using a dynamic extension that computes fundamental matrices. Our observers achieve finite time convergence when no disturbances ... -
Observer design and output feedback Stabilization of time varying systems
Ahmed, Saeed (Bilkent University, 2018-07)We study observer design and output feedback stabilization of switched and nonlinear time varying systems. To establish the stability of feedback switched systems with delay, we develop a new extension of a recently ... -
Output feedback stabilization by reduced order finite time observers using a trajectory based approach
Malisoff, M.; Mazenc, F.; Ahmed, Saeed (IEEE, 2019)We use finite time reduced order continuous-discrete observers to solve an output feedback stabilization problem for a class of nonlinear time-varying systems whose outputs contain uncertainty. Unlike earlier works, our ... -
Reduced order finite time observers for time-varying nonlinear systems
Mazenc, F.; Ahmed, Saeed; Malisoff, M. (Institute of Electrical and Electronics Engineers Inc., 2019)We build reduced order finite time observers for a large class of nonlinear time-varying continuous-time systems. We illustrate our results using a tracking problem for nonholonomic systems in chained form. -
State feedback stabilization of switched systems with delay: trajectory based approach
Mazenc, F.; Ahmed, Saeed; Özbay, Hitay (IEEE, 2017)We present a new trajectory based approach for state feedback stabilization of switched linear continuous-time systems with a time-varying input delay. In contrast with finding classical common Lyapunov function or multiple ...
