Summary
This study presents a small-scale hybrid test setup for the investigation of various vibration control strategies to limit the motion of wind-turbine generators during the installation phase. The control strategy is incorporated virtually (i.e., the response of the additional degrees of freedom is simulated virtually) and is applied on the physical structure by means of an electromagnetic actuator. A Nonlinear Energy Sink (NES) is investigated as a passive control strategy. Preliminary results show that the NES leads to a vibration reduction, but it is much less efficient than a previously proposed active mitigation strategy. The hybrid test setup described in this work can serve as a preliminary experimental investigation into the optimum vibration mitigation strategy for different applications.
