Passive Fault Tolerant Lateral Controller Design For an UAV

IFAC-PapersOnLine, 2018
Abstract In this study a passive lateral fault tolerant controller for an UAV is designed using dynamic inversion (DI) method and robust integral of the signum of the error (RISE) techniques. The details of the methods are summarized. As the reference model of the tracking controller, UAV controlled by feedback type controller is used and the control

Passive Fault Tolerant Control of PEMFC air feeding system [PDF]

International Journal of Hydrogen Energy, 2016
In this paper, a Passive Fault Tolerant Control strategy dedicated to air feeding system fault based on an auto-tuning PID regulator is designed and implemented on a real fuel cell test bench. The present work compares the auto-tuning PID strategy performance to classical PID controller and highlights its benefits during faulty operation.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Optimal Passive Fault Tolerant Control of a High Redundancy Actuator [PDF]

IFAC Proceedings Volumes, 2009
The High Redundancy Actuator (HRA) project deals with the construction of an actuator using many redundant actuation elements. If one element fails, this changes the behaviour slightly, but the system still remains operation. A key challenge in this project is to design a passive fault tolerant controller that maintains the required performance in the ...

Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.
