Robust finite-frequency H2 analysis of uncertain systems with application to flight comfort analysis

Robust finite-frequency H2 analysis of uncertain systems, Report no. LiTH-ISY-R-3011

In many applications, design or analysis is performed over a nite-frequency range of interest. The importance of the H2/robust H2 norm highlights the necessity of computing this norm accordingly. This paper provides di erent methods for computing upper bounds on the robust nite-frequency H2 norm for systems with structured uncertainties. An application of the robust nite-frequency H2 norm for a...

Robust finite-frequency H2 analysis, Report no. LiTH-ISY-R-2973

Finite-frequency H2 analysis is relevant to a number of problems in which a priori information is available on the frequency domain of interest. This paper addresses the problem of analyzing robust finite-frequency H2 performance of systems with structured uncertainties. An upper bound on this measure is provided by exploiting convex optimization tools for robustness analysis and the notion of ...

Robust H2 switching gain-scheduled controller design for switched uncertain LPV systems

In this article, a new approach is proposed to design robust switching gain-scheduled dynamic output feedback control for switched uncertain continuous-time linear parameter varying (LPV) systems. The proposed robust switching gain-scheduled controllers are robustly designed so that the stability and H2-gain performance of the switched closed-loop uncertain LPV system can be guaranteed even und...

Primal and dual robust counterparts of uncertain linear programs: an application to portfolio selection

This paper proposes a family of robust counterpart for uncertain linear programs (LP) which is obtained for a general definition of the uncertainty region. The relationship between uncertainty sets using norm bod-ies and their corresponding robust counterparts defined by dual norms is presented. Those properties lead us to characterize primal and dual robust counterparts. The researchers show t...
