Active versus passive fault-tolerant control of a redundant multirotor UAV [PDF]
The Aeronautical Journal, 2019 ABSTRACTThis paper considers actuator redundancy management for a redundant multirotor Unmanned Aerial Vehicle (UAV) under actuators failures. Different approaches are proposed: using robust control (passive fault tolerance), and reconfigurable control (active fault tolerance).

Noise effect on Grover algorithm
, 2007 The decoherence effect on Grover algorithm has been studied numerically through a noise modelled by a depolarizing channel. Two types of error are introduced characterizing the qubit time evolution and gate application, so the noise is directly related ...

Active fault tolerant control for nonlinear systems with simultaneous actuator and sensor faults [PDF]
, 2013 The goal of this paper is to describe a novel fault tolerant tracking control (FTTC) strategy based on robust fault estimation and compensation of simultaneous actuator and sensor faults. Within the framework of fault tolerant control (FTC) the challenge

Fault tolerant control design of floating offshore wind turbines [PDF]
, 2016 This work is concerned with active vibration mitigation in wind turbines (WT) but not through the use of specifically tailored devices. Instead, a general control scheme is designed for torque and pitch controllers based on a super-twisting algorithm ...

Adaptive Signal Processing Strategy for a Wind Farm System Fault Accommodation [PDF]
, 2018 In order to improve the availability of offshore wind farms, thus avoiding unplanned operation and maintenance costs, which can be high for offshore installations, the accommodation of faults in their earlier occurrence is fundamental.
