Fuzzy Observer-Based Prescribed Performance Control of Vehicle Roll Behavior via Controllable Damper

open access: yesIEEE Access, 2019
This paper presents a novel observer-based control strategy to improve the vehicle roll behavior performance through magneto-rheological (MR) dampers under steering wheel input and various road excitation conditions.

Expressing an observer in preferred coordinates by transforming an injective immersion into a surjective diffeomorphism

open access: yes, 2018
When designing observers for nonlinear systems, the dynamics of the given system and of the designed observer are usually not expressed in the same coordinates or even have states evolving in different spaces. In general, the function, denoted $\tau$ (or

H-infinity adaptive observer enhancements for vehicle chassis dynamics-based navigation sensor fault construction

open access: yesInternational Journal of Advanced Robotic Systems, 2020
The issues of chassis dynamics-based navigation sensor fault and state estimation in land vehicles are specialized in this study. Owing to the essential attributes of robust theory-based observers, an H-infinity adaptive observer is proposed to implement

Observer-Based Controller Design for Systems on Manifolds in Euclidean Space

open access: yes, 2018
A method of designing observers and observer-based tracking controllers is proposed for nonlinear systems on manifolds via embedding into Euclidean space and transversal stabilization.

Unheard and Under‐Supported: Health‐Related Quality of Life in Children, Adolescents, and Young Adults With Sickle Cell Disease

open access: yesPediatric Blood &Cancer, EarlyView.
Abstract Background Sickle cell disease (SCD) is an autosomal recessive hemoglobinopathy affecting millions of individuals worldwide. The clinical expression and psychosocial burden of SCD vary widely across geographical, cultural, and healthcare system contexts, underscoring the need for setting‐specific approaches to assessment.

Filtered Observer-Based IDA-PBC Control for Trajectory Tracking of a Quadrotor

open access: yesIEEE Access, 2021
In this paper, a new filtered observer-based IDA-PBC (Interconnection and Damping Assignment-Passivity Based Control) strategy is developed for trajectory tracking of a quadrotor in the presence of disturbances and model uncertainties.

The Dynamics of Group Codes: Dual Abelian Group Codes and Systems

open access: yes, 2004
Fundamental results concerning the dynamics of abelian group codes (behaviors) and their duals are developed. Duals of sequence spaces over locally compact abelian groups may be defined via Pontryagin duality; dual group codes are orthogonal subgroups of
