|Abstract:||The track-induced self-excited vibration is a special problem that exists in EMS (Electromagnetic Suspension) maglev systems. In this paper, the stability of the electromagnet-track coupled model is examined, and it is found that the second order vibration mode of the track may cause instability problem. To suppress the self-excited vibration, an LMS (Least Mean Square) adaptive cancellation scheme is presented, and a phase locked loop is employed to generate a reference signal for the LMS algorithm. Analysis and simulation show that the proposed adaptive cancellation algorithm is effective in suppressing the vibration with unknown frequency.|
