A new active controller for vibration reduction of secondary structures is studied. The secondary structure is exemplified by a steel Euler beam. The output electromagnetic force from an electric current whirling machine is used as controller force. The excitation is given by a shake table to represent earthquake ground motion. The effectiveness of the controller is examined by varying the phase angle and electromagnetic force amplitude of the electric current whirling machine. We quantify the effectiveness as equivalent added modal damping of the Euler beam.
