Coherence resonance in a network of FitzHugh-Nagumo systems: interplay of noise, time-delay and topology [PDF]

open access: yes, 2017
We systematically investigate the phenomena of coherence resonance in time-delay coupled networks of FitzHugh-Nagumo elements in the excitable regime.

Lyapunov matrices approach to the parametric optimization of time-delay systems

open access: yesArchives of Control Sciences, 2015
In the paper a Lyapunov matrices approach to the parametric optimization problem of time-delay systems with a P-controller is presented. The value of integral quadratic performance index of quality is equal to the value of Lyapunov functional for the ...

Frequency performance analysis of proportional integral-type active disturbance rejection generalized predictive control for time delay systems

open access: yesSystems Science & Control Engineering, 2022
To improve the performance of the Active Disturbance Rejection Control (ADRC) in systems which have large time delay, reduce online computation for Proportional Integral-type Generalized Predictive Control (PI-GPC) method, the Proportional Integral-type ...

Exponential stability of abstract evolution equations with time delay [PDF]

open access: yes, 2014
We consider abstract semilinear evolution equations with a time delay feedback. We show that, if the $C_0$-semigroup describing the linear part of the model is exponentially stable, then the whole system retains this good property when a suitable ...

Trajectory Tracking Control for Reaction–Diffusion System with Time Delay Using P-Type Iterative Learning Method

open access: yesActuators, 2021
This paper has dealt with a tracking control problem for a class of unstable reaction–diffusion system with time delay. Iterative learning algorithms are introduced to make the infinite-dimensional repetitive motion system track the desired trajectory. A

Arbitrary Coefficient Assignment by Static Output Feedback for Linear Differential Equations with Non-Commensurate Lumped and Distributed Delays

open access: yesMathematics, 2021
We consider a linear control system defined by a scalar stationary linear differential equation in the real or complex space with multiple non-commensurate lumped and distributed delays in the state.

Consensus of Multi-Agent Systems with Unbounded Time-Varying Delays

open access: yesApplied Sciences, 2021
In multi-agent systems with increasing communication distances, the communication delay is time-varying and unbounded. In this paper, we describe the multi-agent system with increasing communication distances as the discrete-time system with non ...

Lyapunov Matrices Approach to the Parametric Optimization of a System with Two Delays

open access: yesArchives of Control Sciences, 2016
In the paper a Lyapunov matrices approach to the parametric optimization problem of time-delay systems with two commensurate delays and a P-controller is presented. The value of integral quadratic performance index of quality is equal to the value of the

Influence of information flow in the formation of economic cycles

open access: yes, 2005
A microscopic approach to macroeconomic features is intended. A model for macroeconomic behavior based on the Ausloos-Clippe-Pekalski model is built and investigated. The influence of a discrete time information transfer is investigated. The formation of

Analysis of a Fractional-order Glucose-Insulin Biological System with Time Delay

open access: yesChaos Theory and Applications, 2022
In the human glucose-insulin regulatory system, diverse metabolic issues can arise, including diabetes type I and type II, hyperinsulinemia, hypoglycemia, etc. Therefore, the analysis and characterization of such a biological system is a must. It is well
