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) Webb13 sep. 2024 · The passivity-based control (PBC) is the most practical non-linear control technique due to its simplicity and easy implementation [ 24 ]. 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 ].
