We study the dynamics of the single and coupled van der Pol-Duffing oscillators. Each
oscillator is characterized by the multistability (the coexistence of attractors). Some of the …

This paper presents a four-dimension hyperchaotic Lorenz system, obtained by adding a
nonlinear controller to Lorenz chaotic system. The hyperchaotic Lorenz system is studied by …

A hyperjerk system is a dynamical system, which is modelled by an nth order ordinary
differential equation with n 4 describing the time evolution of a single scalar variable …

This paper investigates the problem of finite-time drive-response synchronization for a class
of neural networks with discontinuous activations, time-varying discrete and infinite-time …

In this research work, a twelve-term novel 5-D hyperchaotic Lorenz system with three
quadratic nonlinearities has been derived by adding a feedback control to a ten-term 4-D …

Hyperchaotic systems are defined as chaotic systems with more than one positive Lyapunov
exponent. Combined with one null Lyapunov exponent along the flow and one negative …

This paper proposes a novel fuzzy adaptive controller for achieving an appropriate
generalized projective synchronization (GPS) of two incommensurate fractional-order …

In this article, the problems of finite-time/fixed-time synchronization have been investigated
for discontinuous neural networks in the unified framework. To achieve the finite-time/fixed …

In this research work, a ten-term novel hyperchaotic system with an exponential nonlinearity
and three quadratic nonlinearities has been derived. The Lyapunov exponents of the …

The stability conditions in fractional order hyperchaotic systems are derived. These
conditions are applied to a novel fractional order hyperchaotic system. The proposed system …
