Roban: A Parameter Robustness Analysis Tool and its Flight Control Applications

In this paper some applic<ltions of the software ROBAN. developed <It the Centro It<lliano Ricerche Aerosp<lziali (Cl RA). <Ire illustmted. ROBAN h<ls been developed to <In<llyse st<lbility and pcrform<lnces (in terms of eigenvalues location on the complex plane) of linear systems subject to uncertain pammeters, and has been shown to be particularly useful to deal with the robustness problems which arise in the !light control tield. In particular. after a description of the algorithm. the applications of ROBAN to analyse a) Robustness in !light conditions. b) Robustness against sensor failures, c) Robustness with respect to PlO are discussed.
