VIBRATION CONTROL DEVICE

摘要

Provided is a vibration control device capable of obtaining a favorable vibration control effect within a permissible stroke range of a movable mass. This vibration control device is equipped with a controller (20) for: obtaining the displacement deviation between the target displacement of a movable mass (3) and the displacement of the movable mass (3) detected by a mass displacement sensor, and/or the speed deviation between the target speed of the movable mass (3) and the speed of the movable mass (3) detected by a mass speed sensor; and generating a control command for causing a motor (4) to drive the movable mass (3) on the basis of the displacement deviation and/or the speed deviation. The vibration control device is characterized in that the target displacement and the target speed are set in a manner such that the amplitude of the movable mass (3) is constant and the phase thereof trails behind the swing of a building (2) by only 90°.
