Abstract

Viscous friction
occurs between the roller guide shoes and guide rail because of the grease
layer.This friction causes to vibration on the cage. This study’s aim is an
investigation and active control of that vibration for passengers. Initially,
the passenger elevator’s dynamics modeling is carried out by Linear Graph
Method. The DC motor and AC motor parameters are used in the system modeling
separately. Then, vibrations occurred on the elevator cabin are observed.
Finally, the effect of vibrations is reduced with the aid of an active
controller. The time and frequency responses are compared for two kinds of the
motor.
