The passivity theorem
Webb10 apr. 2024 · The passive system has an elegant property that the stored energy of the system goes to zero as time goes to infinity, in the absence of an external supply. However, for many practical purposes, it is expected that the stored energy should go to zero in … Webb0 Introduction The thrust of this chapter is the systematic use of the concept of passivity, which plays an essential role in circuit theory and, more generally, in physics. The first …

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 http://limdj.com/nonlinear/Chapter6Lec2.pdf

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 ].
