Optimal Robustness of Port-Hamiltonian Systems [PDF]
SIAM Journal on Matrix Analysis and Applications, 2020 We construct optimally robust port-Hamiltonian realizations of a given rational transfer function that represents a passive system. We show that the realization with a maximal passivity radius is a normalized port-Hamiltonian one. Its computation is linked to a particular solution of a linear matrix inequality that defines passivity of the transfer ...

Research on rehabilitation robot control based on port-Hamiltonian systems and fatigue dissipation port compensation [PDF]
Frontiers in Bioengineering and BiotechnologyIntroductionUpper-limb rehabilitation robots have been demonstrated to effectively promote motor recovery in stroke patients. However, in active training modes, control instability may be induced by the nonlinear and time-varying characteristics of ...

Linear Port-Hamiltonian Systems Are Generically Controllable [PDF]
IEEE Transactions on Automatic Control, 2022 The new concept of relative generic subsets is introduced. It is shown that the set of controllable linear finite-dimensional port-Hamiltonian systems is a relative generic subset of the set of all linear finite-dimensional port-Hamiltonian systems.

Observability for port-Hamiltonian systems [PDF]
2021 European Control Conference (ECC), 2021 The class of port-Hamiltonian systems incorporates many physical models, such as mechanical systems in the finite-dimensional case and wave and beam equations in the infinite-dimensional case. In this paper we study a subclass of linear first order port-Hamiltonian systems.

Riesz Bases of Port-Hamiltonian Systems [PDF]
SIAM Journal on Control and Optimization, 2021 The location of the spectrum and the Riesz basis property of well-posed homogeneous infinite-dimensional linear port-Hamiltonian systems on a 1D spatial domain are studied. It is shown that the Riesz basis property is equivalent to the fact that system operator generates a strongly continuous group.

Stochastic Port-Hamiltonian Systems
Journal of Nonlinear Science, 2022 AbstractIn the present work we formally extend the theory of port-Hamiltonian systems to include random perturbations. In particular, suitably choosing the space of flow and effort variables we will show how several elements coming from possibly different physical domains can be interconnected in order to describe a dynamic system perturbed by general ...

Modeling and Analysis of a Three-Terminal-Memristor-Based Conservative Chaotic System
Entropy, 2021 In this paper, a three-terminal memristor is constructed and studied through changing dual-port output instead of one-port. A new conservative memristor-based chaotic system is built by embedding this three-terminal memristor into a newly proposed four ...
