In recent years a new control device to attenuate the vibrations induced in mechanical systems by harmonic excitations has been presented. This opportunity has invited the idea to build up a procedure allowing to identify a closed-loop control algorithm working on the whole record of the response time-history, with coefficients distributed on a suitably chosen range of frequencies, designed in way to control each harmonic component of the forcing function, possibly verifying some optimality criterion.

The procedure has been tested, proving that the results agree with the theoretical treatment, remaining open the question of the choose of the best control strategy for single harmonics.
