On distributed port-hamiltonian process systems [PDF]
IFAC Proceedings Volumes, 2004 In this paper we use the term distributed port-Hamiltonian Process Systems (DPHPS) to refer to the result of merging the theory of distributed Port-Hamiltonian systems (DPHS) with the theory of process systems (PS). Such concept is useful for combining the systematic interconnection of PHS with the thermodynamic-passivity properties of PS.

A Structural Observation on Port-Hamiltonian Systems
SIAM Journal on Control and Optimization, 2023 We study port-Hamiltonian systems on a familiy of intervals and characterise all boundary conditions leading to $m$-accretive realisations of the port-Hamiltonian operator and thus to generators of contractive semigroups. The proofs are based on a structural observation that the port-Hamiltonian operator can be transformed to the derivative on a ...

A Rosenbrock framework for tangential interpolation of port-Hamiltonian descriptor systems
Mathematical and Computer Modelling of Dynamical Systems, 2023 We present a new structure-preserving model order reduction (MOR) framework for large-scale port-Hamiltonian descriptor systems (pH-DAEs). Our method exploits the structural properties of the Rosenbrock system matrix for this system class and utilizes ...

Notch filters for port-Hamiltonian systems [PDF]
2012 American Control Conference (ACC), 2012 In this paper a standard notch filter is modeled in the port-Hamiltonian framework. By having such a port-Hamiltonian description it is proven that the notch filter is a passive system. The notch filter can then be interconnected with another (nonlinear) port-Hamiltonian system, while preserving the overall passivity property.

Geometric Modeling for Control of Thermodynamic Systems
Entropy, 2023 This paper discusses the way that energy and entropy can be regarded as storage functions with respect to supply rates corresponding to the power and thermal ports of the thermodynamic system. Then, this research demonstrates how the factorization of the

Passive Sliding Mode Control Strategy for PCHD Model of MMC in Unbalanced Power Grid
Zhongguo dianli, 2023 When the voltage of the power grid is unbalanced, the DC transmission and distribution system using modular multilevel converters (MMC) as converter devices will encounter problems such as AC current asymmetry and secondary pulsation of active and ...

Port-Hamiltonian Systems [PDF]
, 2016 As described in the previous Chaps. 3 and 4, (cyclo-)passive systems are defined by the existence of a storage function (nonnegative in case of passivity) satisfying the dissipation inequality with respect to the supply rate s(u, y) = uTy. In contrast, port-Hamiltonian systems, the topic of the current chapter are endowed with the property of (cyclo ...
