BARBOSA, Karina A. e TROFINO, Alexandre. LMI techniques for the analysis of descriptor systems. Sba Controle & Automação [online]. 2002, vol.13, n.1, pp. 22-29. ISSN 0103-1759. http://dx.doi.org/10.1590/S0103-17592002000100005.
In this paper we present LMI techniques for the quadratic stability of uncertain continuous and discrete-time descriptor systems. Connections between the quadratic stability of systems with polytopic and norm bounded LFT uncertainties are also presented. Stability conditions are presented for the ''primal'' and ''dual'' systems.
