Abstract
The problem of minimizing, in the H2-norm sense, the effect on the output of an exogenous input signal known with finite preview is solved by means of a dynamic feedforward scheme designed on the basis of spectral factorization techniques. On standard assumptions, stability and robustness with respect to model uncertainties and unaccessible inputs are assumed to be guaranteed by an inner feedback, while the dynamic feedforward unit herein devised is utterly committed to the purpose of taking advantage of the preview available on the signal to be rejected. The design procedure is illustrated by a numerical example.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
