Journal ArticleDOI
Whole-body impedance control of wheeled mobile manipulators
Alexander Dietrich,Kristin Bussmann,Florian Petit,Paul Kotyczka,Christian Ott,Boris Lohmann,Alin Albu-Schaffer +6 more
TL;DR: A whole-body impedance controller for a humanoid robot, which employs an admittance interface to the kinematically controlled mobile platform, and is suitable for compliant manipulation tasks with low-dimensional planning in the task space.
Journal ArticleDOI
Weak form of Stokes-Dirac structures and geometric discretization of port-Hamiltonian systems
TL;DR: The mixed Galerkin discretization of distributed-parameter port-Hamiltonian systems is presented and its geometric approximation by a finite-dimensional Dirac structure and power-preserving maps on the space of discrete power variables are derived.
Journal ArticleDOI
Passivity and Structure Preserving Order Reduction of Linear Port-Hamiltonian Systems Using Krylov Subspaces
TL;DR: A new structure-preserving scheme for the reduction of linear port- Hamiltonian systems with dissipation using Krylov subspaces is presented and it is shown how to choose the projection matrices in order to guarantee the moment matching property and to obtain a passive and thus stable reduced-order model in port-Hamiltonian form.
Journal ArticleDOI
Discrete-time port-Hamiltonian systems: A definition based on symplectic integration
Paul Kotyczka,Laurent Lefèvre +1 more
TL;DR: In this article, the authors introduce a new definition of discrete-time port-Hamiltonian (PH) systems, which results from structure-preserving discretization of explicit PH systems in time.
Journal ArticleDOI
Finite differences on staggered grids preserving the port-Hamiltonian structure with application to an acoustic duct
TL;DR: A finite-difference spatial discretized scheme that preserves the port-Hamiltonian structure of infinite dimensional systems governed by the wave equation is proposed, based on the use of staggered grids for the discretization of different variables of the system.
