Abstract
Since the elevator cage is the space which is surrounded by walls, it is strongly needed that the noise and vibration inside the car is small as much as possible not to get the passengers uncomfortable and/or uneasy. The lateral vibrations during the car operation, especially, is the most important factor that affect the ride comfort. Recently, the development of the technology for the reduction of the lateral vibration is getting more and more inevitable. This paper describes the control characteristics and experimental results of the two main method of active vibration control system; one is the actively controlled roller guide system and another is the active control system installed between car frame and the platform.
