This study presents a synthesis method of a nonstationary optimal controller with a time-varying criterion function for reducing vibration of a time-varying object such as rope of elevator and crane. Moreover, from the viewpoint of wave propagation, we also propose a method of reducing vibration with wave-absorbing controller to remove the reflected waves. As an illustration, the performance of reducing vibration with respect to the rope-sway problem on a high-rise building is examined through numerical calculation. These nonstationary optimal and wave-absorbing controllers are compared with the stationary optimal controller in case that the structure is subjected to Kobe earthquake.
