Abstract
An active vibration suppression apparatus includes a rotating actuator which is fixed to a vibration suppression target and generates a torque in a rotational direction, an inertial load which is connected to the actuator and moves in the rotational direction relative to the vibration suppression target in accordance with a torque of the actuator, and a driving circuit for generating a driving command signal for controlling the inertial load and driving the rotating actuator in accordance with the driving command signal. The rotating actuator rotates/drives the inertial load with a generated torque, and reduces vibrations produced in the vibration suppression target by applying a drive reaction force generated upon rotating/driving the inertial load as a control torque to the vibration suppression target.
