Nonlinear Disturbance Observer-Based Control for a Class of Port-Controlled Hamiltonian Disturbed Systems

open access: yesIEEE Access, 2018
In this paper, a composite control scheme is presented to asymptotically stabilize a class of port-controlled Hamiltonian systems under nonvanishing disturbances.

Discrete-time port-Hamiltonian systems: A definition based on symplectic integration [PDF]

open access: yes, 2018
We introduce a new definition of discrete-time port-Hamiltonian systems (PHS), which results from structure-preserving discretization of explicit PHS in time.

Coupling Nanostructured Plasmon–Strain Microwave Waveguide to Spin Defects in Hexagonal Boron Nitride for High‐Sensitivity Quantum Sensors

open access: yesAdvanced Materials, Volume 38, Issue 24, 27 April 2026.
Coupling of spin‐active VB−$V_B^ - $ defects in hBN with alumina‐coated gold plasmonic nanoresonators (PNRs), integrated into a microwave‐efficient waveguide, constitutes a plasmon‐strain architecture that enhances their photoluminescence and spin contrast. This platform enables a tenfold quantum yield improvement and achieves a DC magnetic sensitivity

Energy-based Hamiltonian approach in H∞ controller design for n-degree of freedom mechanical systems

open access: yesSystems Science & Control Engineering, 2019
This paper studies the energy-based approach for ${H_\infty } $ controller design of $n $-degree of freedom mechanical systems. In this approach, the Hamiltonian function, which is the sum of kinetic and potential energies of the system, is considered as

Port-Hamiltonian descriptor systems

open access: yes, 2017
The modeling framework of port-Hamiltonian systems is systematically extended to constrained dynamical systems (descriptor systems, differential-algebraic equations). A new algebraically and geometrically defined system structure is derived. It is shown that this structure is invariant under equivalence transformations, and that it is adequate also for

Modeling the Probability of Tsunami Fire Ignition Based on Data From the 2011 Tohoku and 2024 Noto Peninsula Earthquakes, With Recommendations to Reduce Emerging Fire Risk in Tsunami Vertical Evacuation Structures

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 5, Page 1116-1133, 25 April 2026.
ABSTRACT Recent tsunamigenic earthquakes in Japan have highlighted the emerging fire hazard triggered by tsunami inundation and its impact on tsunami vertical evacuation (TVE) structures. This new type of fire following earthquake, referred to as “tsunami fires,” may be a potential universal hazard that tsunami‐prone countries face; however, it has not

Integral control of port-Hamiltonian systems: non-passive outputs without coordinate transformation

open access: yes, 2017
In this paper we present a method for the addition of integral action to non-passive outputs of a class of port-Hamiltonian systems. The proposed integral controller is a dynamic extension, constructed from the open loop system, such that the closed loop

Topological Photonic Devices and Circuits at Terahertz Frequencies

open access: yesLaser &Photonics Reviews, Volume 20, Issue 7, 6 April 2026.
This review examines how 3D topological insulators and emerging topological photonic phases enable robust, low‐loss and defect‐immune terahertz devices. Fundamental properties, device implementations and topological transport mechanisms are surveyed, revealing new opportunities for reconfigurable, high‐performance THz components and scalable ...
