ABSTRACT:
An apparatus for guiding and levitating a vehicle. The apparatus comprises a guideway mechanism upon which the vehicle travels. The apparatus is also comprised of a mechanism for actively controlling differential and lateral guidance or differential and vertical levitation strength of the vehicle with respect to the guideway mechanism. The controlling mechanism is electrodynamically reactive with the guideway mechanism. A method for guiding and levitating a vehicle. The method comprises the steps of guiding a vehicle along the guideway with electrodynamic guidance coils. Then, there is the step of actively controlling alternating current through the guidance coils to correspond with guideway curvature so the vehicle is maintained in a stable position relative to the guideway as it moves around a curve in the guideway and experiences roll compensation.
