Abstract
Movable aerodynamic control surfaces are mounted to a MAGLEV vehicle. They operate in combination with magnetically actuated coils that are located in the vehicle and cooperate with coils or metallic sheets located along the vehicle guideway. Sensors provide clearance information concerning the vehicle relative to the guideway as well as translational speed and vehicle rotational measurements. Based on input from these sensors, a computer positions the control surfaces and energizes the magnetic coils so as to unload dynamic forces and stresses imposed by the vehicle while providing smoother vehicle movement indicative of superior passenger comfort.
