<p>In an elevator device, an actuator for generating a vibration-damping force against the lateral vibration of a car is installed in parallel to an elastic body for preventing the lateral vibration. The actuator is controlled by a vibration-damping control unit. The control unit estimates the inherent frequency of the lateral vibration of the car, and finds a gain value based on the estimated inherent frequency and the rigidity value of the elastic body. Then, the damping control part drives the actuator according to an instruction signal with multiplication of the found gain value.</p> |
