A chaotic jerk system with different types of equilibria and its application in communication system

Rajagopal, Karthikeyan; Pham, Viet-Thanh; Çiçek, Serdar; Jafari, Sajad; Karthikeyan, Anitha; Arun, Sundaram (HRČAK, 2020)

In this paper, a new jerk system is designed. This system can display different characters of equilibrium points according to the value of its parameters. The proposed nonlinear oscillator can have both self-excited and ...
A novel class of Chaotic Flows with infinite equilibriums and their application in Chaos-Based communication design using DCSK

Rajagopal, Karthikeyan; Çiçek, Serdar; Khalaf, Abdul Jalil M.; Pham, Viet-Thanh; Jafari, Sajad; Karthikeyan, Anitha; Duraisamy, Prakash (De Gruyter, 2018)

Discovering chaotic systems with interesting features has been of interest in the recent years. One such important and interesting feature is the type and shape of equilibrium points. We introduce a class of chaotic systems ...
A novel class of chaotic systems with different shapes of equilibrium and microcontroller-based cost-effective design for digital applications

Rajagopal, Karthikeyan; Çiçek, Serdar; Pham, Viet-Thanh; Jafari, Sajad; Karthikeyan, Anitha (Springer, 2018)

Constructing chaotic systems with infinite equilibrium points has been of interest in recent years. Many chaotic systems with equilibrium points located on open and closed curve have been published in the literature. A few ...
A novel parametrically controlled multi-scroll chaotic attractor along with electronic circuit design

Rajagopal, Karthikeyan; Çiçek, Serdar; Naseradinmousavi, Peiman; Khalaf, Abdul Jalil M.; Jafari, Sajad; Karthikeyan, Anitha (Springer, 2018)

We propose a novel multi-scroll chaotic system captured through the Chua’s circuit. The novelty of our proposed multi-scroll system roots on the number of scrolls to be controlled by the parameters instead of changing the ...
A simple snap oscillator with coexisting attractors, its Time-Delayed Form, physical realization, and communication designs

Karthikeyan, Rajagopal; Jafari, Sajad; Akgul, Akif; Karthikeyan, Anitha; Çiçek, Serdar; Shekofteh, Yasser (De Gruyter, 2018)

In this paper, we report a novel chaotic snap oscillator with one nonlinear function. Dynamic analysis of the system shows the existence of bistability. To study the time delay effects on the proposed snap oscillator, we ...
Chaotic cuttlesh: king of camouage with self-excited and hidden flows, its fractional-order form and communication designs with fractional form

Karthikeyan, Rajagopal; Çiçek, Serdar; Akgul, Akif; Jafari, Sajad; Karthikeyan, Anitha (American Institute of Mathematical Sciences, 2020)

There are many works on self-excited and hidden attractors. However the relationship between them is less investigated. In this study we present a system which can have both hidden self-excited attractors. Dynamical ...
New hyperchaotic system with single nonlinearity, its electronic circuit and encryption design based on current conveyor

Karthikeyan, Anitha; Çiçek, Serdar; Rajagopal, Karthikeyan; Duraisamy, Prakash; Srinivasan, Ashokkumar (Tübitak, 2021-06-01)

Nowadays, hyperchaotic system (HCSs) have been started to be used in engineering applications because they have complex dynamics, randomness, and high sensitivity. For this purpose, HCSs with different features have been ...
