Multi‐Modal Feature Fusion‐Based Method for Acoustic Signal Analysis of Fastener Loosening in Saturable Reactors

open access: yesIET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
This study proposes a multi‐modal feature fusion (MFF) method for diagnosing loosening fasteners in converter valve saturable reactors. By deeply fusing multi‐source features, it achieves 96% accuracy for noncontact loosening fault detection, offering a novel voiceprint application approach for complex valve halls.

Observability for Nonlinear Systems: Connecting Variational Dynamics, Lyapunov Exponents, and Empirical Gramians

open access: yesCoRR
Observability quantification is a key problem in dynamic network sciences. While it has been thoroughly studied for linear systems, observability quantification for nonlinear networks is less intuitive and more cumbersome. One common approach to quantify observability for nonlinear systems is via the Empirical Gramian (Empr-Gram) -- a generalized form ...

Optimal Control with Limited Sensing via Empirical Gramians and Piecewise Linear Feedback

open access: yes, 2016
This paper is concerned with the design of optimal control for finite-dimensional control-affine nonlinear dynamical systems. We introduce an optimal control problem that specifically optimizes nonlinear observability in addition to ensuring stability of the closed loop system.

On sensor configurations in a lettuce greenhouse via observability analysis using the empirical gramian

open access: yesActa Horticulturae
Estimating crop states accurately through combining measurements and a dynamical model in a data assimilation algorithm is a promising alternative for high tech crop sensing investments. In order to successfully do this, the employed model and chosen sensor configuration need to be observable. This paper demonstrates, in a lettuce greenhouse model, the
