Hamiltonian formulation of distributed-parameter systems with boundary energy flow [PDF]

, 2001
A Hamiltonian formulation of classes of distributed-parameter systems is presented, which incorporates the energy flow through the boundary of the spatial domain of the system, and which allows to represent the system as a boundary control Hamiltonian ...

Lagrangian-Hamiltonian unified formalism for field theory [PDF]

, 2004
The Rusk-Skinner formalism was developed in order to give a geometrical unified formalism for describing mechanical systems. It incorporates all the characteristics of Lagrangian and Hamiltonian descriptions of these systems (including dynamical ...

Information, disturbance and Hamiltonian quantum feedback control [PDF]

, 2000
We consider separating the problem of designing Hamiltonian quantum feedback control algorithms into a measurement (estimation) strategy and a feedback (control) strategy, and consider optimizing desirable properties of each under the minimal constraint ...

Well-posedness and Stability for Interconnection Structures of Port-Hamiltonian Type

, 2019
We consider networks of infinite-dimensional port-Hamiltonian systems $\mathfrak{S}_i$ on one-dimensional spatial domains. These subsystems of port-Hamiltonian type are interconnected via boundary control and observation and are allowed to be of distinct

New results for time reversed symplectic dynamic systems and quadratic functionals

Electronic Journal of Qualitative Theory of Differential Equations, 2012
In this paper, we examine time scale symplectic (or Hamiltonian) systems and the associated quadratic functionals which contain a forward shift in the time variable.

Phase-Space Modeling and Control of Robots in the Screw Theory Framework Using Geometric Algebra

Mathematics, 2023
The following paper talks about the dynamic modeling and control of robot manipulators using Hamilton’s equations in the screw theory framework. The difference between the proposed work with diverse methods in the literature is the ease of obtaining the ...
