Acceleration sensorless levitation control for the hybrid maglev system

To lower the suspension power,permanent magnets were added into the levitation system.A model vehicle with four hybrid magnet poles was designed.It realized the stable levitation on the basis of the expert PID control scheme.Meanwhile,only gap sensor was needed in the proposed system.Compared with the common PID control,the response speed of the proposed system is increased obviously due to the use of the expert system.It is verified that fast,steady and precise levitation can be realized by the proposed strategy through both simulation and experiments.
