Research on Rejecting Load Disturbance for Levitation System of Maglev Train

Due to the geometric constraints and dynamic constraints between the train and track, there exist several factors influencing the levitation control when the train is running on the curve track. These would make the system unstable and sometimes it´s dangerous without an effective control strategy. In this paper, based on state feedback method, according to analysis on acceleration and current feedback, a new control algorithm is presented, considering the two-point levitation model. Simulation results show that load disturbance is restrained on the same condition, and it proves effective.
