%X The stable range of the guideway natural vibration frequencies is studied by analyzing the Hopf bifurcation of the vehicle-coupled-guideway maglev system. The maglev system is controlled by the cascade controller and the connection of the controller's parameters and the frequencies is given. Based on the stable controller, the Hopf bifurcation point corresponding changeless system parameters and variable guideway natural frequencies is calculated by the numerical arithmetic. The stable range of the guideway natural frequencies is obtained using both numerical arithmetic and simulation method. The qualitative restriction between the system mass, controller frequencies, stiffness of the second subsystem and the guideway natural frequencies is explained.
