A set of proposals for improving ride quality in high-speed lift systems is presented, beginning with a mathematical model of the lift system as a computational design tool for the study of vibration-reduction strategies. An overview of the causes and sources of vibrations is also presented. The first is an active suspension system to control resonance in the car/sling isolation; next is the use of an advanced control strategy to implement car-velocity feedback; and noncontacting electromagnetic guide shoes to reduce lateral disturbances in the lift car.
