Abstract
We propose a new simple three-dimensional continuous autonomous model with two nonlinear terms and observe the dynamical behavior with respect to system parameters. This system changes the stability of fixed point via Hopf bifurcation and then undergoes a cascade of a period-doubling route to chaos. We analytically derive the first Lyapunov coefficient to investigate the nature of Hopf bifurcation and also investigate well-separated regions for different kinds of attractors in two-dimensional parameter space. Next, we introduce a time-scale ratio parameter and calculate the slow manifold using geometric singular perturbation theory. Finally, the chaotic state is annihilated by decreasing the value of the time-scale ratio parameter.
