非线性金融系统的分支分析与时滞反馈控制

In this paper the bifurcation and chaos control of nonlinear finance system is investigated。Firstly, by using the distribution of roots to the associate characteristic equation, we obtain the linear stable region and the conditions of ensuring the existence of Hopf bifurcation。Then we analyze the chaos control of finance system using delayed feedback method。By designing appropriate feedback strength and delay, chaotic oscillation is converted into stable equilibrium or periodic orbit。Finally, some numerical simulation are carried out to support the analytic results。
