Adaptive Signal Processing Strategy for a Wind Farm System Fault Accommodation [PDF]

open access: yes, 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.

Attitude Fault-Tolerant Control of Aerial Robots with Sensor Faults and Disturbances

open access: yesDrones, 2023
In this paper, sensor fault diagnosis and fault tolerant control strategy are investigated for quadcopters under sensor faults and disturbances. We propose the fault diagnosis estimation system and the fault-tolerant control (FTC) method.

Fault tolerant control in an unmanned bicycle robot via sliding mode theory

open access: yesIET Cyber-systems and Robotics, 2022
In this work, a new active fault tolerant control (FTC) is developed for an unmanned bicycle robot based on an integration between a sliding mode control (SMC), fault detection (FD), and fault estimation (FE) via a residual signal.

Effect of optimal torque control on rotor loss of fault-tolerant permanent-magnet brushless machines [PDF]

open access: yes, 2002
A faulted phase in a fault-tolerant permanent-magnet brushless machine can result in significant torque ripple. However, this can be minimized by using an appropriate optimal torque control strategy.
