چکیده
This paper, puts in discussion the structural identifiability of LTI Port-Controlled Hamiltonian (PCH) systems, order to develop a specific identification and control theory. is due their remarkable properties power conservation stability under preserving interconnection. The main part presents based approach, with propositions definitions. It on knowledge associated system ports, interconnected by Dirac structure, for selected input signals. In preliminary section, corresponding transfer functions, outputs, Markov parameters, observability conditions, port-observability or infinite Grammians are defined each port. Beside this, port-identifiability concept introduced analysis one proved that between model can be determined analysis, same time PCH structure. As examples demonstrate theory, controlled LC circuit DC motor lossless lossy cases, respectively.

Structural identifiability of linear mamillary compartmental systems
In biology and mathematics compartmental systems are frequently used. System identiica-tion of systems based on physical laws often involves parameter estimation. Before parameter estimation can take place, we have to examine whether the parameters are structurally iden-tiiable. In this paper we propose a test for the structural identiiability of linear mamillary compartmental systems. The meth...
متن کاملEnergy shaping of boundary controlled linear port Hamiltonian systems
In this paper, we consider the asymptotic stabilization of a class of one dimensional boundary controlled port Hamiltonian systems by an immersion/reduction approach and the use of Casimir invariants. We first extend existing results on asymptotic stability of linear infinite dimensional systems controlled at their boundary to the case of stable Port Hamiltonian controllers including some physi...
متن کاملDiscrete port-Hamiltonian systems
Either from a control theoretic viewpoint or from an analysis viewpoint it is necessary to convert smooth systems to discrete systems, which can then be implemented on computers for numerical simulations. Discrete models can be obtained either by discretizing a smooth model, or by directly modeling at the discrete level itself. One of the goals of this paper is to model port-Hamiltonian systems...
متن کاملOn Higher-order Linear Port-Hamiltonian Systems and Their Duals ?
We formulate a behavioral approach to higher-order linear port-Hamiltonian systems. We formalize constitutive laws such as power conservation, storage and (anti)dissipative relations, and we study several properties of such systems. We also define the dual of a given port-Hamiltonian behavior.
