Abstract EN
EMS-type maglev system is essentially nonlinear and unstable.
It is complicated to design a stable controller for maglev system which is under large-scale disturbance and parameter variance.
Theory analysis expresses that this phenomenon corresponds to a HOPF bifurcation in mathematical model.
An adaptive control law which adjusts the PID control parameters is given in this paper according to HOPF bifurcation theory.
Through identification of the levitated mass, the controller adjusts the feedback coefficient to make the system far from the HOPF bifurcation point and maintain the stability of the maglev system.
Simulation result indicates that adjusting proportion gain parameter using this method can extend the state stability range of maglev system and avoid the self-excited vibration efficiently.
