Abstract
A vibration suppressing system includes a structural member with respect to which vibration suppression is to be executed, an actuator, having a pair of a fixed member and a movable member, for moving the movable member relative to the fixed member, and a first vibration sensor for measuring vibration of the structural member. A displacement sensor measures a movement distance of the movable member, a second vibration sensor measures vibration of the movable member, and a controller controls the actuator on the basis of outputs from the first vibration sensor, the displacement sensor and the second vibration sensor.
