• Unbalanced rotor
• Energy harvesting
• Vibration amplitude reduction

The synchronization of a controlled unbalanced rotor with a viscoelastically mounted supporting body and force excitation is studied. The existence and stability conditions for the synchronous regime of motion are derived for a general control law by the method of direct separation of motion. Then a control law is developed using speed gradient method in order to transfer maximum energy from the excitation to the rotor. The free parameters of the control law are derived in such a way that the controlled synchronization is stable at the existence limit.
