Claim:
1. A vibration control device for damping a vibration of a structure to be vibration-controlled by driving a movable mass disposed on the structure via an actuator on the basis of the vibration of the structure, comprising: first detection means for detecting at least one of a displacement of the structure, a velocity of the structure, and an acceleration of the structure; second detection means for detecting at least one of a displacement of the movable mass and a velocity of the movable mass; and a controller that calculates at least one of a displacement deviation between a target displacement of the movable mass and the displacement of the movable mass detected by the second detection means and a velocity deviation between a target velocity of the movable mass and the velocity of the movable mass detected by the second detection means, and generates a control command for making the actuator drive the movable mass on the basis of at least one of the displacement deviation and the velocity deviation, wherein the target displacement and the target velocity are set in a manner that an amplitude of the movable mass is constant and that phases thereof are adapted such that the target displacement and the target velocity work to damp the vibration of the structure.
