WebbThe following two theorems present ways to find passivity indices of a system and can be easily derived from previous theorems and definitions. Theorem 7. The nonlinear system (2) has local output feedback passivity (OFP) index of ρ, if conditions in Theorem 3 hold for the largest ρ, where w(u,y) is given as w(u,y) = u⊺y−ρy⊺y. (32) Webbfinite-dimensional model is passive. Based on the passivity theorem,13 a strictly passive output feedback controller with finite gain stabilizes any passive system in an L 2 sense. This implies that very simple controllers can be designed for the passive system. Note that the transfer function considered
