# 基于Washout滤波器的金融系统的分岔控制Bifurcation Control of Finance System Based on Washout Filter

>In this paper, Washout filter is adopted to control Hopf bifurcation in a kind of finance system. The effect of its parameters on the position of bifurcation point is discussed in detail. First of all, the Washout filter is introduced in this paper. And then the distribution of the equilibrium point of the system is analyzed. After that, the influence of the filter’s time constant and the linear gain on the location of bifurcation point is analyzed by adding the Washout filter controller, and changing the position of the Hopf bifurcation point by taking different values. Finally, numerical simulations are provided to verify the accuracy and effective of the theoretical analysis.
