A spectral analysis extension to DEMATEL for strategic leverage points identification

International Transactions in Operational Research, EarlyView.
Abstract Efforts to intervene in complex systems often emphasize influential factors, yet system behavior is equally shaped by the relationships among them. Methods such as Decision‐Making Trial and Evaluation Laboratory (DEMATEL) map causal structures but remain descriptive and do not identify which relationships provide the greatest leverage for ...

Actuator Fault Detection and Identification Using H‐Infinity Filter

IET Circuits, Devices &Systems, Volume 2025, Issue 1, 2025.
Open‐circuit faults (OCFs) in insulated gate bipolar transistors (IGBTs) within single‐phase pulse width modulation (PWM) rectifiers can severely degrade system performance, leading to reduced output voltage, poor power quality, overheating, and safety risks, including electric shocks or fires.

Neuro‐adaptive prescribed performance control for spacecraft rendezvous based on the fully‐actuated system approach

IET Control Theory &Applications, Volume 18, Issue 14, Page 1868-1876, September 2024.
This paper investigates the control problem of spacecraft rendezvous with obstacle constraint, considering the external disturbance forces caused by orbit perturbation. The prescribed performance control–artificial potential function‐based control law is derived, adopting the neuroadaptive method to deal with external interferences. Abstract This paper

A Novel Localized Fast Multipole Method for Computations With Spatially Correlated Observation Error Statistics in Data Assimilation

Journal of Advances in Modeling Earth Systems, Volume 16, Issue 6, June 2024.
Abstract Several observation types (e.g., geostationary satellite and Doppler radar observations) have recently been found to exhibit strong spatial error correlations. Including these error statistics in data assimilation for numerical weather prediction can improve analysis quality and forecast skill.

Robust model reference tracking control for high‐order descriptor linear systems subject to parameter uncertainties

IET Control Theory &Applications, Volume 18, Issue 4, Page 479-494, March 2024.
This paper focuses on the robust model reference tracking control problem for high‐order descriptor linear systems subject to parameter uncertainties. The new robust feed‐forward compensation algorithm is proposed for high‐order descriptor linear systems, which take the first‐ or second‐order descriptor linear systems and high‐order linear systems as ...

Eigenstructure Assignment by State-derivative and Partial Output-derivative Feedback for Linear Time-invariant Control Systems

Acta Polytechnica, 2004
This paper introduces a parametric approach for solving the problem of eigenstructure assignment via state-derivative feedback for linear control time-invariant systems. This problem is always solvable for any controllable systems if the open-loop system
