Hybrid Persistency of Excitation in Adaptive Estimation for Hybrid Systems

open access: yesIEEE Transactions on Automatic Control, 2023
We propose a framework to analyze stability for a class of linear non-autonomous hybrid systems, where the continuous evolution of solutions is governed by an ordinary differential equation and the instantaneous changes are governed by a difference ...

Magnetic equivalent circuit model for unipolar hybrid excitation synchronous machine

open access: yesArchives of Electrical Engineering, 2015
Lately, there has been increased interest in hybrid excitation electrical machines. Hybrid excitation is a construction that combines permanent magnet excitation with wound field excitation.

The Design and Optimization of a Novel Hybrid Excitation Generator for Vehicles

open access: yesWorld Electric Vehicle Journal
Silicon rectifier generators, which are single-excitation generators, are commonly used in vehicles. However, a traditional single-excitation generator cannot satisfy the requirements of modern vehicles due to its low efficiency, high failure rate and ...

Mixed-pole hybrid-excitation machine

open access: yes2014 International Conference on Electrical Machines (ICEM), 2014
This paper presents the concept of a novel hybrid-excitation machine. This machine is of the parallel excitation type and has rotor poles in which both PMs and wound-excitation co-exist to produce the total no load magnetomotive force; for this reason it

Magnetoelastic hybrid excitations in CeAuAl 3 [PDF]

open access: yesProceedings of the National Academy of Sciences, 2019
Nearly a century of research has established the Born–Oppenheimer approximation as a cornerstone of condensed-matter systems, stating that the motion of the atomic nuclei and electrons may be treated separately. Interactions beyond the Born–Oppenheimer approximation are at the heart of magneto-elastic functionalities and instabilities.

Orbital-hybridization-created optical excitations in Li2GeO3 [PDF]

open access: yesScientific Reports, 2021
AbstractThe three-dimensional ternary Li2GeO3 compound presents various unusual essential properties. The main features are thoroughly explored from the first-principles calculations. The concise pictures, the critical orbital hybridizations in Li–O and Ge–O bonds, are clearly examined through the optimal geometric structure, the atom-dominated ...
