双时滞 Mackey-Glass 系统的稳定性和 Hopf 分支
Stability and Hopf bifurcation of M ackey-Glass system w ith tw o time delays
摘要
Abstract
The stability and Hopf bifurcation of Mackey‐Glass system with two time delays are studied . The linear stabilities with one delay and two delays are investigated , respectively . It is found that Hopf bifurcations exist w hen the delays pass through a sequence of critical values , furthermore , the system appears chaotic attractors with large time delays . Then , using the center manifold theorem and the normal form method , the direction and stability of the Hopf bifurcation are determined . In the end , some numerical simulations are carried out for supporting the analytic results .关键词
