Abstract
In this paper, a model for simulation of a developed magnetic suspension system by a linear induction motor is induced. The system has a linear induction motor (LIM) as a primary guide way, and a U-shaped iron core, on which the secondary winding is wound, is set at the center top of the vehicle. The vehicle has no electrical contact with the guide way and the configuration of the system is very simple. In the experimental system, however, it is difficult to decide the parameters. Therefore, the model plays an important role to confirm the stability of the suspended motion and to obtain a stable parameter region. Through several analyses, it is proved that the vehicle can be levitated by the proposed control method. Moreover, it is also cleared that chaotic motions occur at some parameter area in the domain of levitation.
