The maglev suspension system is a typical nonlinear hysteretic system, which has characteristics of essential unstability, nonlinearity and parametric uncertainty. In this paper, a disturbance observer is designed on the basis of conventional PID control model of maglev system. Simulation results denote that: this control method has more advantages in anti-disturbance ability, response speed, stability, robustness, dynamic and static performances compared with the conventional PID control.
