Suppression of Maglev Track-Induced Self-Excited Vibration Using an Adaptive Cancellation Algorithm
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.
