The invention discloses a magnetic-levitation train-bridge self-induced vibration inhibition method removing bridge displacement feedback. Compared with a traditional suspension control law of a magnetic-levitation train, the bridge displacement feedback is removed, the vibration acceleration of an electromagnet is obtained merely through measuring of a vibration acceleration sensor, the vibration displacement of the electromagnet is calculated, and stability of a magnetic-levitation train-bridge coupling system can be achieved based on the suspension control law of the magnetic-levitation train. The occurrence of self-induced vibration is avoided, the capability of passing through a bridge of the magnetic-levitation train at a low speed is improved, the system cost is reduced, and the system reliability is improved.
