Abstract

This paper presents techniques for the reduction of vibration inhigh-rise elevator passenger cabs. Reduction in cab vibrationimproves ride comfort and enables the use of more aggressivemotion profiles thereby shortening travel times. Vibrationreduction is accomplished by input shaping the elevator commandsin a scheduling algorithm based on position. To deal withtransient disturbances, a thoughtfully designed vibration absorberis included. This absorber complements the action of input-shapedcontrol scheme.
