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.

WebbThis theorem is further generalized by virtue of the use of multipliers. By doing so, we extend the applicability of the theorem beyond semi-sectorial systems, and recover the frequency-wise results in [5], [6] for LTI systems. The proposed theorem also extends the passivity theorem when the open-loop systems are causal and stable. Speciﬁcally,
