svt: Singular Value Thresholding in MATLAB [PDF]

open access: yesJournal of Statistical Software, 2017
Many statistical learning methods such as matrix completion, matrix regression, and multiple response regression estimate a matrix of parameters. The nuclear norm regularization is frequently employed to achieve shrinkage and low rank solutions.

Structured singular value of implicit systems [PDF]

open access: yesMathematical Methods in the Applied Sciences, 2020
Implicit systems provide a general framework in which many important properties of dynamic systems can be studied. Implicit systems are especially relevant to behavioural systems theory, the analysis and synthesis of complex interconnected systems, systems identification and robust control.

Singular Value and Structured Singular Value Bounds in Parameter Space [PDF]

open access: yes, 2002
This contribution discusses the mapping of singular value (sigma-) bounds and structured singuar value (mu-) bounds into parameter space. The sigma- and mu- mapping problem is defined to enclose robut design and analysis in parameter space. Real, complex and mixed uncertainty structures are considered.

Robust performance in dynamic positioning systems [PDF]

open access: yesModeling, Identification and Control, 1996
Robust performance of dynamic positioning of surface vessels is considered. The structured singular value, mu, is used as a robustness measure. A tight uncertainty description of the wave disturbance model and performance weight matrices based on ...

A geometrical formulation of the μ-lower bound problem [PDF]

open access: yes, 2009
A new problem formulation for the structured singular value μ in the case of purely real (possibly repeated) uncertainties is presented. The approach is based on a geometrical interpretation of the singularity constraint arising in the μ lower

STRUCTURED SINGULAR VALUES OF SOME GENERALISED STOCHASTIC MATRICES

open access: yesBulletin of the Australian Mathematical Society, 2021
AbstractWe investigate a class of generalised stochastic complex matrices constructed from the class of all doubly stochastic matrices and a special class of circulant matrices. We determine the exact values of the structured singular values of all matrices in the class in terms of the constant row (column) sum.

Design of a H∞ Robust Controller with μ-Analysis for Steam Turbine Power Generation Applications

open access: yesEnergies, 2017
Concentrated Solar Power plants are complex systems subjected to quite sensitive variations of the steam production profile and external disturbances, thus advanced control techniques that ensure system stability and suitable performance criteria are ...

Infrared Small Target Detection via Non-Convex Tensor Rank Surrogate Joint Local Contrast Energy

open access: yesRemote Sensing, 2020
Small target detection is a crucial technique that restricts the performance of many infrared imaging systems. In this paper, a novel detection model of infrared small target via non-convex tensor rank surrogate joint local contrast energy (NTRS) is ...

Uniformly asymptotic stability of second-order linear time-varying systems

open access: yesAdvances in Mechanical Engineering, 2020
This paper is concerned with the stability of second-order linear time-varying systems. By utilizing the Lyapunov approach, a generally uniformly asymptotic stability criterion is obtained by adding the system matrices into the quadratic Lyapunov ...
