State maps from integration by parts [PDF]

, 2011
We develop a new approach to the construction of state vectors for linear time-invariant systems described by higher-order differential equations. The basic observation is that the concatenation of two solutions of higher-order differential equations ...

The Ghost Operator and Its Applications to Reveal the Physical Meaning of Reactive Power for Electrical and Mechanical Systems and Others

IEEE Access, 2017
In science and engineering, many concepts are introduced without a clear physical meaning, e.g., imaginary numbers in mathematics and reactive power in electrical engineering.

Control of finite-dimensional port-Hamiltonian systems [PDF]

, 2009
We discuss in this chapter a number of approaches to exploit the modelstructure of port-Hamiltonian systems for control purposes. Actually, the formulationof physical control systems as port-Hamiltonian systems may lead in somecases to a re-thinking of ...

An Energy-Balancing Perspective of Interconnection and Damping Assignment Control of Nonlinear Systems [PDF]

, 2003
Stabilization of nonlinear feedback passive systems is achieved assigning a storage function with a minimum at the desired equilibrium. For physical systems a natural candidate storage function is the difference between the stored and the supplied ...

Controlled Lagrangian and Hamiltonian Systems [PDF]

, 2002
any control systems are mechanical systems. The unique feature of mechanical systems is the notion of energy, which gives much information on the stability of equilibria.

Port-Hamiltonian formulation of nonlinear electrical circuits [PDF]

, 2021
We consider nonlinear electrical circuits for which we derive a port-Hamiltonian formulation. After recalling a framework for nonlinear port-Hamiltonian systems, we model each circuit component as an individual port-Hamiltonian system.

Comparison of Alternative Port-Hamiltonian Dynamics Extensions to the Thermodynamic Domain Toward IDA-PBC-Like Control: Application to a Heat Transfer Model

Dynamics
The dynamics of port-Hamiltonian systems is based on energy balance principles (the first law of thermodynamics) embedded in the structure of the model. However, when dealing with thermodynamic subsystems, the second law (entropy production) should also ...

Bayesian Inference for Path Following Control of Port-Hamiltonian Systems with Training Trajectory Data

SICE Journal of Control, Measurement, and System Integration, 2020
This paper describes a procedure to design a path following controller of port-Hamiltonian systems based on a training trajectory dataset. The trajectories are generated by human operations, and the training data consist of several trajectories with ...
