Selection of weights of performance and stability for robust control

Abstract

To select the weights of performance (Wl(s)) and robustness sensitivity (W3(s)), that for the time being doesn't have a systematic methodology of design, but rather, it is a translation that the designer should make on the required specifications. For that reason some general rules have been developed to select the weights Wl(s) and W3(s) that are applied to all the problems of robust controllers design in Hinf and H21qg, where Hinf and H21qg are powerful tools for designing robust feedback control systems.
