• Active vibration control
• Jeffcott-like rotor
• Disturbance rejection

An active balancing scheme for a variable rotor speed Jeffcott-like rotor, using a suspension with linear electromechanical actuators, is presented. In addition, an estimation scheme for the perturbation signals induced by the inherent eccentricity on the rotating mechanical system, and a control law synthesized for simultaneous tracking tasks on the rotor speed are proposed. Some simulation results show the fast and efficient performance of the active vibration control scheme for good suppression of variable amplitude and frequency harmonic vibrations associated to the unbalance, as well as an effective estimation of the perturbation signals and robustness of the rotor speed controller. The proposed methodology can be applied for on-line monitoring and fault detection quite common in rotating machinery.
