Hybrid control of the Hopf bifurcation in a delayed logistic growth

In this paper, we investigate the problem of bifurcation control for a delayed logistic growth model. By choosing the timedelay as the bifurcation parameter, we present a Hybrid controler to control Hopf bifurcation. We show that the onset of Hopf bifurcation can be delayed or advanced via a hybeid controller by setting proper controling parameter. Under consideration model as operator Equation, apply orthogonal decomposition, compute the center manifold and normal form we determined the direction and stability of bifurcating periodic solutions. Therefore the Hopf bifurcation of the model became controllable to achieve desirable behaviors which are applicable in certain circumstances.
