Abstract

A control system for compensating for horizontal vibrations in a travelling elevator includes at least one horizontal vibration sensor disposed in a plane wherein high frequency vibrations are spatially filtered. Each sensor is provided with a control circuit that provides control signals to actuators associated with roller guide wheels for applying force against a rail as needed to reduce vibrations.
