The Electro-Magnetic-Suspension (EMS) system with a circle-cross-section rail had been proposed to success the banking of a vehicle while running in curve. In the system, the damping in tilting motion is very small that any disturbance will make the vehicle oscillation without friction. This paper proposes a vibration control system made by the rotor with active control. The feedback control of the rotation of the rotor by sensing tilting angle with gyro sensor realizes equivalently skyhook damper for tilting motion of the vehicle. To avoid the trouble that the vibration control system causes the EMS system fail in stabilizing control for floating, the both control are designed in independent. The Nearly-Zero-Power control method is applied to stabilize EMS system for minimum energy consumption with the hybrid-magnets. Experiments were made and the results verified the capabilities of the vibration control methods proposed in this paper.
