This paper describes effects of the primary suspension and sinusoidal guideway disturban ce of low frequency on vertical motion and feedback control circuit for the levitation system in a controlled-PM LSM Maglev vehicle TR 06 travelling with 300km/h over the guideway with sinusoidal disturbances of low and high frequencies. The primary suspension is designed to satisfy sufficiently the ride comfort limits of cabin acceleration 0.5m/s^2 and jerk 0.5m/s^3,using the steady-state analysis of linearized differential equations of motion. The transient responeses of this levitation system are simulated, and it is found that the sinusoidal disturbance of high frequency hardly affects the responses of cabin and bogie, but strongly affects the control circuit. When the control voltage is not high enough to supply the control current required for the high frequency disturbances, the levitation system becomes unstable and cannot maintain the levitation of Maglev vehicle. This analysis where the effect of the high frequency disturbances due to guideway irreguralities is taken into account is very significant to determine the control voltage and to design the control circuits for the levitation system.
