A Passivity-based Nonlinear Admittance Control with Application to Powered Upper-limb Control under Unknown Environmental Interactions [PDF]

open access: yes, 2019
This paper presents an admittance controller based on the passivity theory for a powered upper-limb exoskeleton robot which is governed by the nonlinear equation of motion.

A Geometric Method for Passivation and Cooperative Control of Equilibrium-Independent Passivity-Short Systems

open access: yes, 2020
Equilibrium-independent passive-short (EIPS) systems are a class of systems that satisfy a passivity-like dissipation inequality with respect to any forced equilibria with non-positive passivity indices.

Passive euthanasia [PDF]

open access: yesJournal of Medical Ethics, 2005
The idea of passive euthanasia has recently been attacked in a particularly clear and explicit way by an “Ethics Task Force” established by the European Association of Palliative Care (EAPC) in February 2001. It claims that the expression “passive euthanasia” is a contradiction in terms and hence that there can be no such thing.

Duality and Network Theory in Passivity-based Cooperative Control

open access: yes, 2013
This paper presents a class of passivity-based cooperative control problems that have an explicit connection to convex network optimization problems. The new notion of maximal equilibrium independent passivity is introduced and it is shown that networks ...

The Road Less Travelled? Pathways from Passivity to Agency in Student Learning

open access: yesCollected Essays on Learning and Teaching, 2015
This qualitative study examined fourth-year undergraduate students’ responses to reflective writing prompts and journal entries related to their practical experiences in two capstone courses, both based in SBL/PBL pedagogies. We examined their ‘strategic’

Dual-Passivity-Based Control Strategy for Energy Storage Converter under Microgrid Operation Mode Switching

open access: yesZhongguo dianli, 2022
At the unfavorable moments such as island startup, island load switching, and unplanned off-grid, the excessive fluctuation of microgrid bus voltage frequency may seriously damage the electrical equipment of the entire microgrid.
