Robust qLPV Tracking Fault-Tolerant Control of a 3 DOF Mechanical Crane

Mathematical and Computational Applications, 2020
The main aim of this paper is to propose a robust fault-tolerant control for a three degree of freedom (DOF) mechanical crane by using a convex quasi-Linear Parameter Varying (qLPV) approach for modeling the crane and a passive fault-tolerant scheme. The

Multidimensional‐Encoded High‐Fidelity Spectrometers With a Floating‐Base Bipolar Junction

Advanced Functional Materials, EarlyView.
A floating‐base bipolar junction photodetector enables multidimensional spectral encoding through synergistic gate‐ and drain‐bias modulation of interfacial barrier matching. The resulting complementary spectral responses form a diverse, weakly correlated response matrix, enabling robust and high‐fidelity spectral reconstruction even at sub‐nanoampere ...

Adaptive Minimum-Entropy Hybrid Compensation for Compound Faults of Non-Gaussian Stochastic Systems

IEEE Access, 2019
This study investigated minimum-entropy hybrid fault-tolerant control (FTC) theory for non-Gaussian stochastic systems with compound faults. After fuzzy linearization for the singular systems, the output probability density function (PDF) is generated by

Software-based fault-tolerant routing algorithm in multidimensional networks [PDF]

, 2006
Massively parallel computing systems are being built with hundreds or thousands of components such as nodes, links, memories, and connectors. The failure of a component in such systems will not only reduce the computational power but also alter the ...

Neuromorphic Devices for Extreme Environments: State‐Variable Reliability and Stabilization Strategies

Advanced Functional Materials, EarlyView.
Neuromorphic devices for extreme environments are interpreted through the physical states that store and process information. Radiation, temperature extremes, and vacuum can perturb vacancies, filaments, trapped charges, polarization, interfaces, and readout signals.

High‐Modulus Skeleton‐Reinforced PDMS Microstamps for Precision Transfer Printing of Microscale Devices

Advanced Functional Materials, EarlyView.
Elastomeric micropillars bend under contact loading, sliding microscale devices out of alignment during transfer printing. A hybrid PDMS stamp embeds a high‐modulus skeleton within each pillar while retaining a compliant contact surface. The reinforcement confines pillar deformation, suppressing interfacial sliding and preserving array registration on ...
