摘要
利用反馈控制方法对一类具HollingⅡ型功能反应的3种群食物链进行混沌控制,用Routh-Hurwitz判定准则研究系统非负系统平衡点的局部稳定性,考虑Hopf分支产生的条件,并通过数值模拟谁控制的有效性.
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.
