will always be kept at 0. The measured structural displacement is given to the controller, which computes the control signal u ( t ) which is the control force for the actuator. The controller will treat any excitation as a disturbance, continuously trying to reject it. In the subsequent paragraphs, the disturbance d in Fig. 1 will be considered as an impulse disturbance.

Description of the practical stand and model identification
The experimental setup has been entirely developed at
identification with a sequence t of length q , referred to as the Talbot sequence. This also permits the restriction of p to values within the range 0 < p < 2 q , or within the non-zero residues mod
2 q , Z 2 q × .
The following results lead to the solution of the Gauss sum as a DFT pair.
[ 31 ] Given two positive and coprime integers , p and q , with 0 < p < 2 q , there exists a unique positive integer s , in the range 0 < s < 2 q , such that :
classical arrow and spoke types at particular frequencies. See figure 10 for a geometric view of this instance.
Special relative equilibria of the body-inclined type.
As a final remark, we would like to point out that, a complete identification of the classical families of relative equilibria involves the use of a complete set of charts, which cover the case in which the axis b 3 is allowed to be the spin-axis.
Conclusions and future work
