Distributed Adaptive Fault-Tolerant Control of Uncertain Multi-Agent Systems [PDF]
, 2015 This paper presents an adaptive fault-tolerant control (FTC) scheme for a class of nonlinear uncertain multi-agent systems. A local FTC scheme is designed for each agent using local measurements and suitable information exchanged between neighboring ...

Acceleration-based fault-tolerant control design of offshore fixed wind turbines [PDF]
, 2016 Wind turbines (WTs) are basically controlled by varying the generator load torque (with the so-called torque control) and the blade pitch angles (with the so-called pitch control) based on measurement of the generator shaft speed.

An application of adaptive fault-tolerant control to nano-spacecraft [PDF]
, 2014 Since nano-spacecraft are small, low cost and do not undergo the same rigor of testing as conventional spacecraft, they have a greater risk of failure.

Model-based fault detection and isolation for wind turbine [PDF]
, 2012 In this paper, a quantitative model based method is proposed for early fault detection and diagnosis of wind turbines. The method is based on designing an observer using a model of the system. The observer innovation signal is monitored to detect faults.
