| Abstract: | Chaos of a three species food chain with Holling Ⅱ functional responses is controlled by using the feedback control method. The criteria of Routh Hurwitz are used to study the local stability of the non-negative equilibrium. The conditions for existence of Hopf bifurcations are given. Finally, the feasibility of controlling is demonstrated through several numerical simulations. |
