This paper proposes a new Electro-Magnetic-Suspension (EMS) system which has the ability of self-banking in curve section. This new EMS system is able to tilt automatically corresponding to the magnitude of the centrifugal force. Four hybrid-magnets (HMs : combination of permanent and electro-magnet) are used to guide and suspend a vehicle at the same time, that is different to a conventional EMS system getting necessary force from a guidance system when running in sharp curve. The Nearly-Zero-Power control method is applied to minimize energy consumption of the HMs. Five degrees of freedom are considered in the simulation and experiment. The results of simulation and experiment show this new EMS system has the ability to tilt automatically corresponding to the magnitude of the centrifugal force, and cancel the constant disturbance forces added in five directions only with the attraction forces of the permanent magnets (PMs) in the HMs and the gravity of earth.
