Coordinated Control Strategies for SMES-Battery Hybrid Energy Storage Systems

IEEE Access, 2017
Power swings may cause power system instability; therefore, hybrid energy storage systems (HESSs) are necessary to smooth the output of wind farms. Superconducting magnetic energy storage (SMES) systems have a high power density, whereas battery energy ...

Discrete port-Hamiltonian systems [PDF]

, 2005
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.

Equivariant singularity theory with distinguished parameters: Two case studies of resonant Hamiltonian systems [PDF]

, 1998
We consider Hamiltonian systems near equilibrium that can be (formally) reduced to one degree of freedom. Spatio-temporal symmetries play a key role. The planar reduction is studied by equivariant singularity theory with distinguished parameters.

Neural network quaternion-based controller for port-Hamiltonian system

Demonstratio Mathematica
In this research article, a control approach for port-Hamiltonian PH systems based in a neural network (NN) quaternion-based control strategy is presented. First, the dynamics is converted by the implementation of a Poisson bracket in order to facilitate

Energy-stable Port-Hamiltonian Systems [PDF]

We combine energy-stable and port-Hamiltonian (pH) systems to obtain energy-stable port-Hamiltonian (espH) systems. The idea is to extend the known energy-stable systems with an input-output port, which results in a pH formulation.

Voice synthesis using power-balanced simulation of a quasi-1D model of the vocal apparatus

Frontiers in Signal Processing
The vocal apparatus is a biophysical dynamic system capable of self-oscillation, which involves fluid–structure interactions and human control. This study on the sound synthesis of voiced sounds presents a physical quasi-1D model of the vocal apparatus ...

An integrated control strategy for D-PMSG wind power generation systems

Zhejiang dianli
Smoothing output power fluctuations of wind power generation systems is crucial for the stable operation of power grid. Based on the port-controlled Hamiltonian （PCH） model， an integrated control strategy for rotor speed tracking and power smoothing in ...
