This note generalizes the port-Hamiltonian formulation of the continuous time primal-dual gradient algorithm for static constrained convex optimization to the convex optimal contro…
Segmented Model-Based Hydrogen Delivery Control for PEM Fuel Cells: a Port-Hamiltonian Approach
Lalitesh Kumar, Jian Chen, Chengshuai Wu +2
This paper proposes an extended interconnection and damping assignment passivity-based control technique (IDA-PBC) to control the pressure dynamics in the fuel delivery subsystem (…
Kron reduction of nonlinear networks
Arjan van der Schaft, Bart Besselink, Anne-Men Huijzer
Kron reduction is concerned with the elimination of interior nodes of physical network systems such as linear resistor electrical circuits. In this paper it is shown how this can b…
Reciprocity of nonlinear systems
Arjan van der Schaft
One of the key contributions of the 1972 seminal paper by Willems was the analysis of symmetry (also called reciprocity) of input-state-output systems, both from an external (input…
Angle-based formation stabilization and maneuvers in port-Hamiltonian form with bearing and velocity measurements
Ningbo Li, Pablo Borja, Arjan van der Schaft +1
This paper proposes a port-Hamiltonian framework for angle-based formation stabilization and maneuvers using bearing and velocity measurements with an underlying triangulated Laman…

In this paper we extend the previously introduced class of boundary port-Hamiltonian systems to boundary control systems where the variational derivative of the Hamiltonian functio…
Comparison of Non-deterministic Linear Systems by -Similarity
Armin Pirastehzad, Arjan van der Schaft, Bart Besselink
We introduce -similarity, a notion of system comparison that measures to what extent two stable linear dynamical systems behave similarly in an input-output sense. This beha…
Differential-algebraic systems with dissipative Hamiltonian structure
V. Mehrmann, A. J. van der Schaft
Different representations of dissipative Hamiltonian and port-Hamiltonian differential-algebraic equations (DAE) systems are presented and compared. Using global geometric and alge…
Port-Hamiltonian systems and monotonicity
M. Kanat Camlibel, Arjan van der Schaft
The relationships between port-Hamiltonian systems modeling and the notion of monotonicity are explored. The earlier introduced notion of incrementally port-Hamiltonian systems is…
Limits to Energy Conversion
Arjan van der Schaft, Dimitri Jeltsema
A consequence of the Second Law of thermodynamics is that no thermodynamic system with a single heat source at constant temperature can convert heat into mechanical work in a recur…
Cyclo-dissipativity revisited
Arjan van der Schaft
Starting from a symmetrization and extension of the basic definitions and results of dissipativity theory we obtain new results on cyclo-dissipativity; in particular their external…
Contracts as specifications for dynamical systems in driving variable form
Bart Besselink, Karl H. Johansson, Arjan van der Schaft
This paper introduces assume/guarantee contracts on continuous-time control systems, hereby extending contract theories for discrete systems to certain new model classes and specif…
An energy-based analysis of reduced-order models of (networked) synchronous machines
T. W. Stegink, C. De Persis, A. J. van der Schaft
Stability of power networks is an increasingly important topic because of the high penetration of renewable distributed generation units. This requires the development of advanced…
