| Abstract: | This paper proposes a new robust chaotic system of three-dimensional
quadratic autonomous ordinary differential equations by introducing
an exponential quadratic term. This system can display a
double-scroll chaotic attractor with only two equilibria, and can be
found to be robust chaotic in a very wide parameter domain with
positive maximum Lyapunov exponent. Some basic dynamical properties
and chaotic behaviour of novel attractor are studied. By numerical
simulation, this paper verifies that the three-dimensional system
can also evolve into periodic and chaotic behaviours by a constant
controller. |
