DYNAMIC CHARACTERISTICS AND CONTROL REQUIREMENTS OF ALTERNATIVE MAGNETIC LEVITATION SYSTEMS

Two fundamentally different approaches to achieving non-contact suspension for high speed (swung dash 300 mph) ground vehicles have been proposed and studied in the United States and other countries. One of the approaches utilizes magnetic repulsive forces (inductive system) and the other utilizes magnetic attractive forces (ferromagnetic system). The inductive system yields a suspension which is stable with constant levitation currents but is poorly damped, while the ferromagnetic system requires a feedback current control system just to achieve a stable levitation equilibrium. The control system requirements and resulting vehicle dynamics for both levitation approaches are discussed in this paper.
