Abstract
In this paper, we investigate the effect of multiple delays on the 3-D simple chaotic system with hidden chaotic attractors coexisting with one stable equilibrium by Wang and Chen. In order to investigate complex dynamics of hidden chaotic attractors with multiple delays, we choose \(\tau _1\) and \(\tau _2\) as bifurcating parameters and consider the stability of equilibrium and the existence of Hopf bifurcations. Some explicit formulas for determining the direction of bifurcations and the stability of bifurcating periodic solutions are obtained by using normal form theory and center manifold theory. The numerical simulations are performed to support the correctness and effectiveness of the analytical results. The effect of multiple delays can be applied to the chaotic system only with one stable node-foci for the purpose of control and anti-control of hidden chaos by delayed switchover. Furthermore, to reach deep and clear understanding of the dynamics of such hidden attractors, circuit implementation of the multiple time-delay system is analyzed using the PSpice.
