چکیده

In this paper, the dynamical behavior of single magnet suspension system of maglev train considering the elastic guide-way is researched through HOPF bifurcation theory. With three states feedback variables (gap, current, velocity), the HOPF bifurcation conditions and corresponding vibration frequency of the coupled system is presented under different flexible guideway conditions, that is, the guideway parameters are changeable. These results can provide with beneficial help for improving the traditional design of flexible guideway and control algorithms.

Dynamic response analysis of single-span guideway caused by high speed maglev train

High speed maglev is one of the most important reformations in the ground transportation systems because of its no physical contact nature. This paper intends to study the dynamic response of the single-span guideway induced by moving maglev train. The dynamic model of the maglev train-guideway system is established. In this model, a maglev train consists of three vehicles and each vehicle is r...

Controller Design for Commercial Maglev Vehicle

An electromagnetic levitation controller design considering guideway deflection is presented. Even though to design a maglev controller to make a vehicle steady suspension under guideway deflection is a key technology in maglev vehicle system, the vehicle-guideway interaction effects haven’t well explored and yet settled. Unlike most approaches based on the linear model, a maglev controller is ...

Hopf bifurcation analysis of a diffusive predator-prey model with Monod-Haldane response

In this paper, we have studied the diffusive predator-prey model with Monod-Haldane functional response. The stability of the positive equilibrium and the existence of Hopf bifurcation are investigated by analyzing the distribution of eigenvalues without diffusion. We also study the spatially homogeneous and non-homogeneous periodic solutions through all parameters of the system which are spati...

HOPF BIFURCATION CONTROL WITH PD CONTROLLER

In this paper, we investigate the problem of bifurcation control for a delayed logistic growth model. By choosing the timedelay as the bifurcation parameter, we present a Proportional - Derivative (PD) Controller to control Hopf bifurcation. We show that the onset of Hopf bifurcation can be delayed or advanced via a PD Controller by setting proper controlling parameter. Under consideration mode...
