This paper proposes a new Electro-Magnetic-Suspension (EMS) system, which has the ability of self-banking in curve section. This new EMS system can tilt automatically corresponding to the magnitude of the centrifugal force. Four hybrid-magnets (HMs) ─ a combination of permanent and electro-magnets ─ are used to guide and suspend a vehicle simultaneously in a manner different from that of a conventional EMS system, which acquires the necessary force from a guidance system while running in a tight curve. The Nearly-Zero-Power control method is applied to minimize energy consumption of the HMs. Five degrees of freedom are considered during the simulation and the experiment. The results of the simulation and the experiment demonstrate that this new EMS system has the ability to tilt automatically corresponding to the magnitude of the centrifugal force and nullify the constant disturbance forces applied in five directions using only the attractive forces of the permanent magnets (PMs) in the HMs and the earth's gravity.
