Paper Abstract
In applications of vibration suppression, control forces ideally act on the structure increasing its damping. While
the frequency response of the structure is guaranteed to have a positive real part under ideal conditions, in
practice a stability limit exists when inertial actuators are used. In this case the system response is no longer
guaranteed to be positive real and so the control system may become unstable at high gains. Moreover, traditional
approaches suggest the use of inertial actuators only if its natural frequency is well below the natural frequency
of the structure, thus preventing their use at low frequencies. This paper proposes an interesting technique to
enlarge the operational range to lower frequencies and to allow the use of inertial actuators. The approach is
numerically tested and experimentally validated on a test rig.
