POWER CONDITIONING SYSTEMS FOR A MAGNETICALLY LEVITATED TEST VEHICLE

The power conditioning for a magnetically levitated linear-motor propelled test vehicle is described. Control circuits have been developed to provide a constant air gap for levitation and improved damping of lateral motion due to force disturbances. Transistorized magnet drivers supply the required magnet current. A longitudinal control system with programmed limits on the second and third derivatives of the position command allows both precise position stopping and control of acceleration and jerk. A programmable controller is used for sequencing and monitoring the levitation and propulsion systems.
