Abstract: A fractional-order delayed SEIR rumor spreading model with a nonlinear incidence function is established in this paper, and a novel strategy to control the bifurcation of this model is proposed. First, Hopf bifurcation is investigated by considering time delay as bifurcation parameter for the system without a feedback controller. Then, a state feedback controller is designed to control the occurrence of bifurcation in advance or to delay it by changing the parameters of the controller. Finally, in order to verify the theoretical results, some numerical simulations are given.

Key words: rumor spreading, fractional-order, time delay, bifurcation control
