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 ...

An Enhanced Smith Predictor Based Control System Using Feedback-feedforward Structure for Time-delay Processes

open access: yesThe Journal of Engineering Research, 2017
This paper presents enhanced Smith predictor based control systems (SPBCSs) for processes with a time-varying or fixed time delay. This work focuses on improving the arrangement and asynchrony of SPBCS components rather than the design of the predictor ...

Delay-dependent exponential stability of neutral stochastic delay systems [PDF]

open access: yes, 2009
This paper studies stability of neutral stochastic delay systems by linear matrix inequality (LMI) approach. Delay dependent criterion for exponential stability is presented and numerical examples are conducted to verify the effectiveness of the proposed

Design of controllers for time delay systems: Integrating and unstable systems [PDF]

open access: yes, 2016
The paper deals with design of controllers for integrating and unstable time delay systems. The proposed method is based on the Padé first order time delay approximation. The control system with two feedback controllers is considered.

On Global Exponential Stability Preservation under Sampling for Globally Lipschitz Delay-Free and Retarded Systems

open access: yes, 2016
The paper shows that the global exponential stability property is preserved, under suitable fast sampling, whenever the dynamics of the system at hand is described by globally Lipschitz functions.

Synchronization of circadian rhythms in the scale of a gene, a cell and a whole organism [PDF]

open access: yesКомпьютерные исследования и моделирование, 2013
In the paper three characteristic scales of a biological system are proposed: microscopic (gene's size), mesoscopic (cells size) and macroscopic level (organisms size).

Fault-Tolerant Control of Multi-UAV Attitude Based on Predictive Control in Uncertain Network Environment

open access: yesIEEE Access
This paper analyzes the simultaneous occurrence of actuator faults (AF) and sensor faults (SF) in a Multi-Unmanned Aerial Vehicle (UAV) system operating in an unreliable network environment, and designs a distributed fault-tolerant control (FTC) scheme ...

Ovarian Sex Cord Stromal Tumors in Children and Adolescents—The European Standard Clinical Practice Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT As part of the European Cooperative Study Group for Paediatric Rare Tumours initiative, we developed standard clinical practice guidelines for ovarian sex cord stromal tumors, based on comprehensive national and international cohort analyses, literature review, and a final expert consensus conference.

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.
