A new LPV modeling approach using PCA-based parameter set mapping to design a PSS

Journal of Advanced Research, 2017
This paper presents a new methodology for the modeling and control of power systems based on an uncertain polytopic linear parameter-varying (LPV) approach using parameter set mapping with principle component analysis (PCA).

Performance change detection and recovery in inferential control loops

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract In most industrial environments, soft sensors are crucial for estimating variables that are hard to measure. It is critical that these variables be estimated quickly and accurately because they are closely linked to plant safety and profit. Therefore, performance drift in the soft sensors cannot be ignored.

Robust gain-scheduled controller design for uncertain LPV systems: Affine quadratic stability approach

Journal of Electrical Systems and Information Technology, 2014
Our paper deals with robust gain-scheduled controller design for uncertain LPV systems which ensures closed-loop stability and guaranteed cost for all scheduled parameter changes. The novel procedure is based on LPV paradigm, Lyapunov theory of stability

Fixed-order LPV Controller Design for LPV Systems by Convex Optimization

IFAC Proceedings Volumes, 2013
In this paper a new method for fixed-order output-feedback Linear Parameter Varying (LPV) controller design is presented. First, a set of stabilizing LPV controllers is given as an inner convex approximation of the non-convex set of all stabilizing LPV controllers with the same order.

Resolving a Complex Neonatal Phenotype by Rapid Trio Whole‐Genome Sequencing: A De Novo 11q14.3–q22.3 Deletion and a Splicing‐Altering Synonymous ANK1 Variant

Journal of Clinical Laboratory Analysis, EarlyView.
Clinical utility of trio WGS and time metrics in a neonate with congenital anomalies and hemolytic anemia. ABSTRACT Background Neonates with complex and evolving phenotypes often lack sufficiently specific clinical features to guide targeted genetic testing.

Convolutional Neural Networks for Very Low-Dimensional LPV Approximations of Incompressible Navier-Stokes Equations

Frontiers in Applied Mathematics and Statistics, 2022
The control of general nonlinear systems is a challenging task in particular for large-scale models as they occur in the semi-discretization of partial differential equations (PDEs) of, say, fluid flow.

Voice and Speech in Atypical Parkinsonian Disorders

Movement Disorders Clinical Practice, EarlyView.
Background Motor speech disorders are early, common, and functionally limiting features of atypical parkinsonian disorders (APDs) such as progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and multiple system atrophy (MSA). These impairments are underrecognized and undertreated in neurology clinics.
