Full‐order observer design for quadratic port‐controlled Hamiltonian systems

open access: yesAsian Journal of Control, EarlyView.
Abstract The full‐order observer design problem for a particular class of port‐controlled Hamiltonian systems is approached in this paper. The proposed full‐order observer scheme belongs to the structure preserving class of dynamic estimators as it preserves the natural stability properties of the approached class of systems that are useful for the ...

x-y duality in topological recursion for exponential variables via quantum dilogarithm

open access: yesSciPost Physics
For a given spectral curve, the theory of topological recursion generates two different families $\omega_{g,n}$ and $\omega_{g,n}^\vee$ of multi-differentials, which are for algebraic spectral curves related via the universal $x-y$ duality formula.

Analogies between Knots and Primes, 3-Manifolds and Number Rings [PDF]

open access: yesarXiv, 2009
This is an expository article of our work on analogies between knot theory and algebraic number theory. We shall discuss foundational analogies between knots and primes, 3-manifolds and number rings mainly from the group-theoretic point of view.

Transfer Learning‐Based Data‐Fusion Model Framework for State of Health Estimation of Power Battery Packs

open access: yesBattery Energy, EarlyView.
To handle nonlinearity and feature coupling, a data‐driven aging model is proposed, employing dual Gaussian Process Regressions and transfer learning to enhance model efficiency and accuracy. Adaptive filtering refines the model by integrating aging features and output capacity, resulting in a closed‐loop data fusion framework for SOH estimation ...
