An electro-dynamic Magnetic Levitation vehicular system has been modelled and studied. In practice, a MagLev vehicle will consist of a number of cars which are mechanically coupled to each other. It is reasonable to assume that each of these cars will be independently controlled with the help of a supervisory controller. This thesis deals with the control aspects of one such car. The car is equipped with two control magnets one at the front end and the other at the rear end. The currents in these magnets can be varied to provide levitation and pitch-axis control. The rotational aspects of the vehicle about the yaw and roll axes is neglected here. The car has also a horizontal thrust producing mechanism, the dynamics of which has been neglected. A controller has been devised using frequency domain analysis. It is shown that the vehicle Can be controlled effectively to meet nominal ride specifications. These specifications are derived both from the point of practical implementation of the vehicle and from the need to ensure good ride quality. The controller needs to be robust in its operation. This thesis shows that a simple controller configuration is enough to maintain satisfactory operation for a variety of operating conditions. It is also shown that in the event of a disrupted magnet circuit, normal operation can be restored with a backup set, without having to stop the vehicle or endanger its occupants. This study is entirely conceptual and no attempt has been made to practically implement the system. It should also be noted that a reasonable choice was made for the parameters of the model, that compares closely to data from existing MagLev systems. / Graduation date: 1991
