Taking the 200km/h maglev vehicle as the research object, The Simulink model of single levitation frame with double loop feedback control is established by using the vertical electromagnetic force expression under the action of longitudinal eddy current. By using German high-speed low interference spectrum as the dynamic input, the influence of controller parameters of maglev levitation system under the action of longitudinal eddy current is compared and analyzed. The results show that the longitudinal eddy current will cause the deviation of the balance point of levitation gap, and the increase of air gap coefficient will restrain the longitudinal eddy current to some extent; The increase of velocity coefficient can reduce the fluctuation range of levitation gap, but it will aggravate the vibration acceleration response of levitation frame; Increasing the acceleration coefficient can effectively reduce the vibration acceleration response of the levitation frame, but it will expand the fluctuation range of the levitation gap.
