ABSTRACT

The paper presents the progress of control development for mechatronic guidance within the DLR-internal project Next Generation Train. It reports on the implementation of the control on the experimental running gear hardware operated at the scale 1:5 roller rig at DLR. The state feedback control synthesis utilizes the parameter space approach in order to explicitly consider varying conicities. A feed-forward controller is introduced by model inversion. The resulting control performance is demonstrated by measurements. Then, the approach is transferred and applied to a full scale multibody model of the NGT train set. Specific measures are required to account for gyroscopic effects in transition curves, where the superelevation of the track is inor decreasing. Simulation results document the achievements of the control design and validate the underlying considerations.
