An optimization approach for worst-case fault detection observer design [PDF]

, 2004
This paper deals with the fault detection problem for linear system with unknown inputs. The H∞, norm and H_ index are employed to measure the robustness to unknown inputs and the fault sensitivity, respectively. Furthermore, by using the pole assignment

Multimodal Data‐Driven Microstructure Characterization

Advanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

On minimal degree simultaneous pole assignment problems

Linear Algebra and its Applications, 2002
The main objective of this paper is to find the smallest possible integer \(q\) such that the closed-loop characteristic polynomials of a generic \(r\)-tuple of linear systems of degrees \(n_1,\dots, n_r\), respectively, can be arbitrarily assigned by a single dynamic compensator of degree not exceeding \(q\).

CONDITIONING OF STATE FEEDBACK POLE ASSIGNMENT PROBLEMS

Taiwanese Journal of Mathematics, 2012
In [26,27,35], condition numbers and perturbation bounds were produced for the state feedback pole assignment problem (SFPAP), for the single- and multi-input cases with simple closed-loop eigenvalues. In this paper, we consider the same problem in a different approach with weaker assumptions, producing simpler condition numbers and perturbation ...
