Resumen:
The problem of modelling uncertainty in aerospace exible structures is addresed in thispaper by a non conservative characterization of the regions containing the perturbed eigenvalues ofa real modal state-space realization. A description of the uncertainty associated with the naturalfrequencies and damping factors is obtained through a Linear FractionalTransformation formulation.With this approach, a less conservative family of models is obtained which can be incorporated to thestandard robust control formulation. Simulation results are presented to illustrate the application ofthis approach on a exible structure
