Analysis and design of linear parameter varying systems using LMIs

Revista Iberoamericana de Automática e Informática Industrial RIAI, 2019
This paper presents a tutorial on analysis and design of linear parameter varying (LPV) systems using linear matrix inequalities (LMIs). Several specifications, such as D-stability, guaranteed H∞ performance and guaranteed quadratic cost, as well as ...

Interlesion Time as a Key Metric of Procedural Proficiency in Atrial Fibrillation Ablation: From Fellow to Attending

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Attending EPs performed ablation with shorter ILT, which likely contributed to more efficient procedures and reduced overall ablation time. ABSTRACT Introduction Pulmonary vein isolation (PVI) is a cornerstone of atrial fibrillation (AF) ablation. Unlike balloon‐based or pulsed field ablation, radiofrequency ablation requires precise catheter control ...

Electrophysiological Characteristics of Atrial Fibrillation Trigger Sites During Ongoing Atrial Fibrillation Using Ultra‐High‐Resolution Mapping

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
AF trigger sites exhibited a markedly shorter minimum local cycle length during ongoing AF, suggesting transient rapid activity. Ultra‐high‐resolution mapping during ongoing AF may provide complementary mechanistic information when conventional trigger mapping is inconclusive.

Asymptotic Model Matching for LPV Systems

, 2018
We consider the problem of forcing the output of a given Linear Parameter Varying (LPV) plant to match asymptotically that of a given LPV model using a static or a dynamic feedback control law that also quadratically stabilizes the plant.

The Efficacy of Left Atrial Appendage Occlusion During Thoracoscopic Epicardial AF Ablation for Improving Rhythm and Cardiac Function in Patients With Heart Failure

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Thoracoscopic epicardial AF ablation in heart failure improved LV systolic function irrespective of left atrial appendage occlusion (LAAO). Concomitant surgical LAAO was associated with fewer LPV reconnections without worsening postoperative diastolic function, while atrial tachyarrhythmia recurrence was similar between groups.

Periodic Scenario Trees: A Novel Framework for Robust Periodic Invariance and Stabilization of Constrained Uncertain Linear Systems

International Journal of Robust and Nonlinear Control, Volume 36, Issue 9, Page 5069-5086, June 2026.
ABSTRACT This work proposes a new framework for stabilizing uncertain linear systems and for determining robust periodic invariant sets and their associated control laws for constrained uncertain linear systems. Necessary and sufficient conditions for stabilizability by periodic controllers are stated and proven using finite step Lyapunov functions for

Robust Control of Wind Turbines by Using Singular Perturbation Method and Linear Parameter Varying Model

Journal of Control Science and Engineering, 2016
The maximum power point tracking problem of variable-speed wind turbine systems is studied in this paper. The wind conversion systems contain both mechanical part and electromagnetic part, which means the systems have time scale property.

Robust Time-Varying Parameter Estimation of Uncertain LPV Systems Subject to Estimated States

IEEE Access
In recent years, many techniques for parameter estimation have been developed, with special attention given to the case of time-varying parameters, as they can describe a wide range of physical systems.
