ABSTRACT: An analytical and experimental evaluation was made of the stability and dynamic characteristics of a small scale magnetically levitated vehicle. The vehicle was levitated over a variety of guideway perturbations in an attempt at stimulating unstable modes of oscillation, No instabilities developed in the five degrees of freedom measured using either passive or ·active damping. The analytical model was used to simulate the observed motions of the vehicle using a computer, Reasonable agreement was found although more damping was observed than was simulated using the model. This work was performed as a part of the Federal Railroad Administration's program of research and development on high speed ground transportation for use in intercity passenger service.
