摘要 利用特征值理论和奇异摄动,得到了一类具有反馈控制的广义Logistic时滞系统的唯一正平衡态渐近稳定和发生Hopf分支的充分条件,通过若干实例验证了理论分析和数值计算的一致性。 Hopf bifurcation of a generalized Logistic model with feedback regulation are investigated. By using the theory of eigenvalues and singular pertubation,some sufficient conditions under which a sequence of Hopf bifurcations occur at the positive equilibrium are obtained. Some examples are also given.
