Abstract
In the superconducting magnetically levitated transport (Maglev) system is a focus of interest as a future mode of ultra high speed transport. The purpose of this study is to improve ride comfort of Maglev vehicles by reducing vibrations of the vertical and pitching motions of the middle and tail cars using optimal preview control theory. In this study, secondary suspension installed actuators and applies to LQ and optimal preview control. Simulations verify that preview control enable to reduce vibration both transient and steady-state response compared with optimal control.
