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 Memristive Hyperjerk Chaotic System: Amplitude Control, FPGA Design, and Prediction with Artificial Neural Network

Wang, Ran; Li, Chunbiao; Çiçek, Serdar; Rajagopal, Karthikeyan; Zhang, Xin (Hindawi, 2021)

An amplitude controllable hyperjerk system is constructed for chaos producing by introducing a nonlinear factor of memristor. In this case, the amplitude control is realized from a single coefficient in the memristor. The ...
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 ...
Dynamical analysis, FPGA implementation and its application to chaos based random number generator of a fractal Josephson junction with unharmonic current-phase relation

Kingni, Sifeu Takougang; Rajagopal, Karthikeyan; Çiçek, Serdar; Cheukem, Andre; Tamba, Victor Kamdoum; Fautso Kuiate, Gaetan (Springer, 2020)

The dynamical characteristics and its applications to random number generator of a fractal Josephson junction with unharmonic current-phase relation (FJJUCPR) described by a linear resistive-capacitive-inductance shunted ...
Fractional-Order Analysis of Modified Chua’s Circuit System with the Smooth Degree of 3 and Its Microcontroller-Based Implementation with Analog Circuit Design

Wang, Junxia; Rajagopal, Karthikeyan; Akgul, Akif; Çiçek, Serdar; Aricioglu, Burak (MDPI, 2021)

In the paper, we futher consider a fractional-order system from a modified Chua’s circuit system with the smooth degree of 3 proposed by Fu et al. Bifurcation analysis, multistability and coexisting attractors in the the ...
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 ...
