Gradient Extremum Seeking with Time-Varying Delays
2018 Annual American Control Conference (ACC), 2018This paper presents a gradient extremum seeking algorithm to cope with locally quadratic static maps under time-varying delays. Dealing with non constant delays has a strong impact in the predictor design in terms of the associated transport partial differential equation (PDE) with variable convection speeds as well as the conditions imposed on the ...

Stability of uncertain systems with time-varying delays
Fifth World Congress on Intelligent Control and Automation (IEEE Cat. No.04EX788), 2004This paper provides a new criterion for robust asymptotical stability of a class of uncertain systems with multiple time-varying delays and nonlinear uncertainties based on LaSalle theorem. Firstly, we gave a contractive invariant set for time-delay systems, and then we derived the condition in which the system would be attracted into this invariant ...

Teleoperation via Internet with Time-Varying Delay
2006 13th IEEE International Conference on Electronics, Circuits and Systems, 2006This paper propose a novel approach for modeling the end-to-end time delay dynamics of the Internet using system identification, and use it for controlling real-time Internet-based telerobotic operations. When a single model is used, it needs to adapt to the operating conditions before an appropriate control mechanism can be applied.

Delay-dependent stability of DC Microgrid with time-varying delay
2016 22nd International Conference on Automation and Computing (ICAC), 2016In order to optimize the efficiency of renewable energy sources they are connected in a form of AC and DC Microgrids. Furthermore the increased number of DC loads has shifted the view to DC Microgrids. This paper presents the stability and maximum time delay calculation for a DC Microgrid implementing master-slave control strategy.

Optimal estimation for systems with time-varying delay
2007 46th IEEE Conference on Decision and Control, 2007In this paper, the optimal estimation problem for discrete-time systems with time-varying delay in the measurement channel is studied. First, under the assumption that the time-varying delay is of a known upper bound, the single delayed measurement can be rewritten as multiple channel measurements that contain the same state information as the original

Scheduling in networks with time-varying channels and reconfiguration delay
2012 Proceedings IEEE INFOCOM, 2012We consider the optimal control problem for networks subjected to time-varying channels, reconfiguration delays, and interference constraints. We show that the simultaneous presence of time-varying channels and reconfiguration delays significantly reduces the system stability region and changes the structure of optimal policies.

DELAY-DEPENDENT ASYMPTOTIC STABILITY OF NEURAL NETWORKS WITH TIME-VARYING DELAYS
International Journal of Bifurcation and Chaos, 2008This paper considers the problem of stability analysis for neural networks with time-varying delays. The time-varying delays under consideration are assumed to be bounded but not necessarily differentiable. In terms of a linear matrix inequality, a delay-dependent asymptotic stability condition is developed, which ensures the existence of a unique ...

Delay-dependent exponential stability of delayed neural networks with time-varying delay
IEEE Transactions on Circuits and Systems II: Express Briefs, 2006In this brief, free-weighting matrices are employed to express the relationship between the terms in the Leibniz-Newton formula; and based on that relationship, a new delay-dependent exponential-stability criterion is derived for delayed neural networks with a time-varying delay.

Stability of Lurie Time-Varying Systems with Time-Varying Delay Feedbacks
2018In this chapter, the stability problems of Lurie nonlinear system with time-varying plant and time-varying actuator under time-varying delay feedback are presented. First, absolute stability criteria, which we define as solvable matrix inequalities, are outlined by constructing a Lyapunov–Razumikhn functional.
