Active mass damper (AMD) mounting on the cage of super- high- speed elevators has been developed for the purpose of reducing horizontal vibrations of cages excited by forced displacements from elevator guide rails. By anticipated disturbances, such as, the cage excitation by passenger or vertical vibration of the cage, the control stability of AMD could be disrupted, which was especially sensitive to gravity components detected by acceleration sensors. Therefore, a new AMD controller, which was designed based on LQ optimal control theory, and the installation of high pass filters were considered. Excellent advantages of the AMD system having the proposed control synthesis were successfully demonstrated by numerical simulation and also actual high speed elevators running in the field, and the stability of the controller and the reduction of 30-40% in horizontal vibration were finely realized.
