【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.更多还原
