The passivity theorem

Webbtheorem vs. passivity theorem, and robust stability and absolute stability. 4.2.1 Robust stability The terminologies used in this chapter are mainly followed from [ZD98] Definition 6. Given the description of an uncertainty model set P and a set of performance objectives, suppose P 2P is the nominal design model and K is the resulting controller. 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)

The PBC reshapes the dissipated energy from the system’s Euler–Lagrange representation and then injects a virtual resistance matrix to dampen the system and ensure its passivity [ 25 ].

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,
