Magnetically Actuated Microrobot for Drug Delivery: Current Progress and Challenges

Advanced Robotics Research, EarlyView.
Magnetically actuated microrobots are reshaping targeted drug delivery through wireless propulsion, programmable materials, and localized therapeutic release. This review examines how fabrication, body material selection, structural architecture, loading mechanisms, and imaging‐guided control converge to enable microrobotic therapies while identifying ...

Consensus Formation and Change are Enhanced by Neutrality

Advanced Science, EarlyView.
Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.

In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

Advanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Fault tolerant control of a gyroscope system

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
This paper presents an experimental study of a control moment gyroscope using a new controller architecture, generalized internal model control, which separates the controller design into two stages: (a) a nominal performance controller and (b) a robustness controller.

Coverage in fault-tolerant control

Automatica, 2004
This paper deals with a two-level framework for the analysis, design, and operation of a fault tolerant system, where the upper level is a stochastic discrete state continuous time system describing a slower failure process, and the lower level is a conventional deterministic continuous state system in which top level states are embedded as parameters.

Fault tolerance of decentralized adaptive control

Proceedings ISAD 93: International Symposium on Autonomous Decentralized Systems, 2002
A decentralized adaptive control system, in which the local feedback gains are tuned by the sigma -modified adaptive law so as to achieve small output errors with small feedback gains, is proposed. Stability analysis and fault tolerance analysis are performed, and it is shown that if the stability of one of the stable subsystems breaks down and if the ...

Concepts and methods in fault-tolerant control

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
Faults in automated processes will often cause undesired reactions and shut-down of a controlled plant, and the consequences could be damage to technical parts of the plant, to personnel or the environment. Fault-tolerant control combines diagnosis with control methods to handle faults in an intelligent way.

Fault-Tolerant Control

1994
The increasing complexity of modern engineering production systems and requirements for high quality products have created a need for control systems with fault-tolerance. This chapter presents two algorithms for fault-tolerance analysis and fault-tolerant controller design.
