Abstract EN
This paper deals with passive monomodal vibration control by shunting piezoelectric actuators to electric impedances constituting the series of a resistance and an inductance.
Although this kind of vibration attenuation strategy has long been employed, there are still unsolved problems; particularly, this kind of control does suffer from issues relative to robustness because the features of the electric impedance cannot be adapted to changes of the system.
This work investigates different algorithms that can be employed to optimise the values of the electric components of the shunt impedance.
Some of these algorithms derive from the theory of the tuned mass dampers.
First a performance analysis is provided, comparing the attenuation achievable with these algorithms.
Then, an analysis and comparison of the same algorithms in terms of robustness are carried out.
The approach adopted herein allows identifying the algorithm capable of providing the highest degree of robustness and explains the solutions that can be employed to resolve some of the issues concerning the practical implementation of this control technique.
The analytical and numerical results presented in the paper have been validated experimentally by means of a proper test setup.
