Fault-tolerant formation control of wheeled mobile robots using energy-balancing methods

, 2022
The problem of fault-tolerant formation control for a team of wheeled robots is addressed. The multi-agent network is represented as the passive interconnection of port-Hamiltonian systems, and trajectory-tracking is achieved by using passivity arguments.

Efficacy of Intermittent Theta‐Burst Stimulation for Prolonged Disorders of Consciousness: A Prospective, Randomized, Controlled Trial

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Emerging evidence suggests that low‐frequency neural oscillations are dynamically regulated by consciousness levels, with the recovery of low cortical activity potentially serving as a neurophysiological substrate for conscious emergence. Targeted enhancement of these low‐frequency rhythms in patients with disorders of consciousness

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 ...

A mixed active and passive GLR test for a fault tolerant control system

International Journal of Applied Mathematics and Computer Science, 2012
A mixed active and passive GLR test for a fault tolerant control system This paper presents an adaptive Generalized Likelihood Ratio (GLR) test for multiple Faults Detection and Isolation (FDI) in stochastic linear dynamic systems. Based on the work of Willsky and Jones (1976), we propose a modified generalized likelihood ratio test, allowing ...
