SIMPLE MEMRISTIVE TIME-DELAY CHAOTIC SYSTEMS
International Journal of Bifurcation and Chaos, 2013Memristive systems have appeared in various application fields from nonvolatile memory devices and biological structures to chaotic circuits. In this paper, we propose two nonlinear circuits based on memristive systems in the presence of delay, i.e. memristive systems in which the state of the memristor depends on the time-delay.

Encryption with synchronized time-delayed systems
Physical Review E, 2005We propose a new communication scheme that uses time-delayed chaotic systems with delay time modulation. In this method, the transmitter encodes a message as an additional modulation of the delay time and then the receiver decodes the message by tracking the delay time. We demonstrate our communication scheme in a system of coupled logistic maps.

Generalized synchronization in time-delayed systems
Physical Review E, 2005We investigate the generalized synchronization between two unidirectionally linearly and nonlinearly coupled chaotic nonidentical Ikeda models and find existence conditions of the generalized synchronization. Also we study the chaos synchronization between nonidentical Ikeda models with variable feedback-delay times and find the existence and ...

Almost all the physical systems and processes in the real world are nonlinear [1] in nature, so over the years a considerable attention has been paid to the investigation of the dynamic behaviour of nonlinear systems. Development of nonlinear control technique has serious demerits of difficult analytical framework, computational issues and specific ...

Deterministic Time Delay Systems
2002It is clear from the examples given previously that the the investigation of the class of dynamical time delay systems is of great importance in dealing with the world economy. It is why much attention has been paid to this class of systems by many researchers from different communities.

Time delays in metabolic control systems
Biosystems, 1988In this work we use mathematical models with discrete and distributed time delays to analyse the stability of metabolic pathways controlled by end product. We assume the kinetics of the intermediates of the path to be unknown, and we cover the lack of information by using a time delay.

Disturbance Decoupling of Time Delay Systems
Asian Journal of Control, 2015AbstractA necessary and sufficient condition is derived for the solvability of the disturbance decoupling problem by a pure shift dynamic compensator. It corrects previously obtained results for multi‐input multi‐output (MIMO) systems. Also, necessary and sufficient conditions are given for the solvability of the problem by a dynamic compensator for ...

Input Modeling in Time-Delayed Systems
Computational Mathematics and Modeling, 2001An essentially heuristic approach is proposed for the design of a controller of a plant responding with an appreciable but not a dominating delay (in the sense described by Minorsky). The usefulness and the practical efficiency of that approach can be judged fairly at present only by a practitioner of the corresponding engineering speciality.

Stabilization of Neutral Time-Delay Systems
2009This paper addresses the stabilization problem for neutral time-delay systems. Starting from a transfer approach, we develop a general algebraic framework for the study of the stabilization. The stability considered in this paper is the exponential one.

In this chapter, we consider stability, performance analysis, and control of linear (probably, uncertain) discrete-time systems. Some of the presented ideas may also be useful in the nonlinear case. Differently from continuous-time TDSs, the discrete-time ones can be reduced to non-delay systems by state/input/output augmentation.
