Abstract

Vehicle-coupling-rail vibration is ubiquitous in maglev system. Taking the vehicle-rail system as the research object, the reason why the vehicle-coupling-rail vibration arises is analyzed when the classical feedback is utilized. A new method is presented to suppress the vehicle-coupling-rail vibration. This method is derived by utilizing the differential of suspension clearance in the classical feedback control method. Because it is difficult to obtain the differential signal for the disturbance of noise, a technique that can restrain noise is introduced to obtain the differential of suspension clearance. The effectiveness of the proposed algorithm is evaluated by both simulation and experiment.
