In this paper, we investigate the effect of delayed feedbacks on the generalized Sprott B system with hidden attractors and its local Hopf bifurcation. We choose the delay as the parameter, and the existence of local Hopf bifurcations are verified. By using the normal form theory and the center manifold theorem, we obtain the explicit formulae for determining the stability and direction of bifurcated periodic solutions. Finally, numerical simulations indicate that delayed feedback control plays an effective role in control of chaos.
