Parallel distributed compensation scheme for chaotic masking system via Rivest cipher 4 stream cipher

open access: yesIET Control Theory & Applications, 2023
This study presents a design methodology for Takagi‐Sugeno (T‐S) fuzzy models‐based secure communications in multiple time‐delay chaotic (MTDC) systems with Rivest cipher 4 (RC4) algorithm.

A discrete epidemic model for bovine Babesiosis disease and tick populations

open access: yesOpen Physics, 2017
In this paper, we provide and study a discrete model for the transmission of Babesiosis disease in bovine and tick populations. This model supposes a discretization of the continuous-time model developed by us previously.

Adaptive Sliding Mode Control for a Double Fed Induction Generator Used in an Oscillating Water Column System

open access: yesEnergies, 2018
Wave power conversion systems are nonlinear dynamical systems that must endure strong uncertainties. Efficiency is a key issue for these systems, and the application of robust control algorithms can improve it considerably.

Biologically inspired adaptive intelligent secondary control for MGs under cyber imperfections

open access: yesIET Cyber-Physical Systems, 2019
In this study, the authors investigate the secondary control of microgrids (MGs) in the presence of cyber imperfections such as delay and/or noise, and system disturbances.

Enabling cyber-physical demand response in smart grids via conjoint communication and controller design

open access: yesIET Cyber-Physical Systems, 2019
This study proposes a novel user-centric cyber-physical framework to achieve distributed demand response (DDR) in a distribution system where local schedulers (LS) present at individual buses program both local and non-local loads to reduce the maximum ...

Asymptotic behaviours of stochastic differential delay equations [PDF]

open access: yes, 2006
Most of the existing results on stochastic stability use a single Lyapunov function, but we shall instead use multiple Lyapunov functions in this paper.

DNN identification and fault-tolerant control for non-linear systems with unknown faults

open access: yesThe Journal of Engineering, 2019
In this study, dynamical neural networks (DNNs) are used as an online identifier for a class of non-linear systems with unknown actuator faults. By integrating the designed non-linear FD observer with adaptive regulation algorithm, the parameter coupling

Distributed finite-time information discovery-based secondary restoration for islanded microgrids

open access: yesIET Smart Grid, 2019
A new finite-time secondary voltage and frequency restoration scheme for an islanded microgrid (MG) is proposed in this study. All distributed generators (DGs) do not have access to the voltage and frequency reference value which makes their control more
