Energy-balanced models for acoustic and audio systems: a port-Hamiltonian approach†
نویسندگان
چکیده
Port-Hamiltonian systems (PHS) are an extension of Hamiltonian systems, which represent open passive systems which are structured according to their conservative and dissipative parts, as well as the external sources. They are widely used in engineering as a central tool for the modelling of physical systems, their passive-guaranteed simulation, as well as for control issues, see e.g. [1]. In this paper, we shall recall the definition of the port-Hamiltonian systems and give some indication on how they might be used for the modelling and simulation of electro-acoustic systems, which are illustrated on some applications.

Energy-storage Balanced Reduction of Port-hamiltonian Systems
Supported by the framework of dissipativity theory, a procedure based on physical energy to balance and reduce port-Hamiltonian systems with collocated inputs and outputs is presented. Additionally, some relations with the methods of nonlinear balanced reduction are exposed. Finally a structure-preserving reduction method based on singular perturbations is shown.

متن کاملPassive Guaranteed Simulation of Analog Audio Circuits: A Port-Hamiltonian Approach
We present a method that generates passive-guaranteed stable simulations of analog audio circuits from electronic schematics for real-time issues. On one hand, this method is based on a continuous-time power-balanced state-space representation structured into its energy-storing parts, dissipative parts, and external sources. On the other hand, a numerical scheme is especially designed to preser...
متن کاملInterpolation-based H2 model reduction for port-Hamiltonian systems
Port network modeling of physical systems leads directly to an important class of passive state space systems: port-Hamiltonian systems. We consider here methods for model reduction of large scale port-Hamiltonian systems that preserve port-Hamiltonian structure and are capable of yielding reduced order models that satisfy first-order optimality conditions with respect to an H2 system error met...
متن کاملBalanced realization and model order reduction for port-Hamiltonian systems
This paper is concerned with nonlinear model order reduction for electro-mechanical systems described by port-Hamiltonian formulae. A novel weighted balacend realization and model order reduction procedure is proposed which preserves port-Hamiltonian structure as well as stability, reachability and observability of the original system. This implies that one can utilize the intrinsic physical pr...
متن کاملPort Hamiltonian System in Descriptor Form for Balanced Reduction: Application to a Nanotweezer
This paper proposes a method of balanced model reduction for constrained linear port Hamiltonian systems. Constrained linear port Hamiltonian systems are first written in a canonical descriptor form such that the Hamiltonian structure is preserved. The computations of the controllability and observability Gramians are then used to derive the balanced port Hamiltonian representation of the syste...
