A New Design of the Maglev Line System and Study on the Control Strategy

Abstract:

For solution of the vehicle-guideway coupling vibration in the maglev system, a new structure of the maglev line system was proposed. With the aim to verify the feasibility of the scheme, a numerical model of the single magnet suspension system on the new line was founded. Using the state observer developed in this paper, the magnetic track's vibration states were introduced to the control system, and a controller was proposed with the state feedback method. The impacts of the main parameters of the new maglev line were investigated in the end. The results shows that the control method can maintain the stability of the maglev system even the cement beam has no damp; The response of magnet has nothing to do with the relative position between the magnet and the cement beam, which makes the design of the controller and the solution of the vehicle-guideway coupling vibration easy; in addition, increasing of the track mass and decreasing of the track pad stiffness are also conductive to the system stability.
