Abstract
A method and system for compensating vibrations in an elevator car, which elevator car is guided on at least one guide rail, the vibrations being detected by at least one sensor at a source of disturbance by at least another sensor at an affected point on the elevator car. Both detected vibrations are interpreted by a control to drive a compensating mass on the elevator car to neutralize the vibrations at the affected point by a compensating force of opposite sign and equal amount.
