Active suspensions are usually applied for control of secondary suspensions because of the restrictions of hardware. Since magnetic levitation vehicles have heavy unsprung masses of superconductive magnets and have no viscous damping at high velocity, it is supposed that the characteristic of their vibrations is worse than that of ordinary vehicles. On the other hand, magnetic levitation vehicles have the advantage that primary suspension can also be actively controlled. This is because the force in the primary suspension is generated by electro magnetic force. In this paper, it is shown that unsprung mass resonance is decreased by use of direct control of primary suspension. Frequency responses which are calculated for an optimal regulator are compared, and the characteristics of secondary suspension control and of primary suspension control are clarified.
