Modelling and control of an adaptive tuned mass damper based on shape memory alloys and eddy currents

The paper illustrates the layout and the model of the whole damper and validates it. This model moreover evidences all the advantages allowed by the new layout proposed. Finally, two different strategies to control the dynamic characteristics of the new adaptive tuned mass damper are presented and compared, both numerically as well as experimentally, so to illustrate strengths and drawbacks of each. The experiments and the simulations show that this new damper is fully capable of functioning when random excitation acts as disturbance on the system to control.
