Abstract
The Electro-Magnetic-Suspension (EMS) system with a circle-cross-section rail succeeded the banking of a vehicle while running in curve. In the system, the damping for tilting motion is generated by the actively controlled rotor, which realizes equivalently skyhook damper for tilting motion. When the vehicle runs in a curved truck at high speed, the effects of disturbance cannot be ignored in both levitation and rolling control. In this paper, the improvement of control ability for any disturbance is considered. First, minimal-order observer and disturbance observer are used as levitation control. Next, damping performance of skyhook damper for rolling control is investigated while varying the position of the rotor. Simulation and experiment are made and the effectiveness of the proposed system is verified.
