Abstract :
Output feedback stabilization of uncertain linear systems is analyzed. A necessary and sufficient condition of quadratic stability of the closed-loop system is introduced. An algorithm is proposed to test the stability of the system. It computes ρ, an uncertainty stability margin coefficient, in a two-level optimization algorithm where the region of uncertainty is approximated by a convex hyperpolyhedron
