3306 Vibration Control for High-Speed Elevator using Active Mass Damper

Abstract

Skyscrapers require installment of high-speed elevators. As the elevators become faster, their ride comfort worsens because of cabin vibration due to disturbance. Therefore, an active vibration control system is often utilized to improve the ride comfort. In this study, a vibration control system and a neutral position control system are designed based on optimal control theory using the Active Mass Damper (AMD) to improve the ride comfort and prevent incorrect movement of the AMD. This report investigates the effect of a variable gain control on the movement of the AMD using computer simulation.
