Robust Trajectory Tracking Control for Fully Actuated Marine Surface Vehicle
In this paper we present a robust trajectory tracking control for a fully actuated marine surface vehicle. The tracking controller is obtained using a port-Hamiltonian model of the marine craft and includes an integral action to compensate for constant ...

Casimir-Based Control Beyond the Dissipation Obstacle
A prevailing trend in the stabilization of port-Hamiltonian systems is the assumption that the plant and the controller are both passive. In the standard approach of control by interconnection based on the generation of Casimir functions, this assumption

Two Types of Non‐Abelian Topological Phase Transitions Under Duality Mapping in 1D Photonic Chains
In this work, two types of non‐Abelian phase transitions are revealed. The first type is the braided‐node type, signified by the Dirac degeneracy node moving into or out of the unit circle. The second type corresponds to the emerging of nodal‐line degeneracy which intersects with unit circles.

Weak Form of Stokes-Dirac Structures and Geometric Discretization of Port-Hamiltonian Systems
We present the mixed Galerkin discretization of distributed parameter port-Hamiltonian systems. On the prototypical example of hyperbolic systems of two conservation laws in arbitrary spatial dimension, we derive the main contributions: (i) A weak ...

This paper proposes an adaptive‐velocity sensorless control strategy for freight trains using multiple electric locomotives operating under external disturbances. The control strategy is designed based on a non‐recursive control framework with a time‐varying control parameter. The elimination of velocity sensors is achieved through a high‐gain observer

Port-Hamiltonian Systems: Network Modeling and Control of Nonlinear Physical Systems [PDF]
It is shown how port-based modeling of lumped-parameter complex physical systems (multi-body systems, electrical circuits, electromechanical systems,..) naturally leads to a geometrically defined class of systems, called port-Hamiltonian systems. These are Hamiltonian systems defined with respect to a power-conserving geometric structure capturing the ...

We consider the dynamics of an elastic continuum under large deformation but small strain. Such systems can be described by the equations of geometrically nonlinear elastodynamics in combination with the St. Venant-Kirchhoff material law.

Coordinated Control Strategies for SMES-Battery Hybrid Energy Storage Systems
Power swings may cause power system instability; therefore, hybrid energy storage systems (HESSs) are necessary to smooth the output of wind farms. Superconducting magnetic energy storage (SMES) systems have a high power density, whereas battery energy ...

On switched Hamiltonian systems [PDF]
In this paper we study the well-posedness and stability of a class of switched linear passive systems. Instrumental in our approach is the result, also of interest in its own right, that any linear passive input-state-output system with strictly positive
