Active Disturbance Rejection Control for Wind Turbine Fatigue Load

open access: yesEnergies, 2022
With the participation of wind power in grid frequency modulation, the fatigue load of the wind turbine increases accordingly. A new control method that considers both fatigue load and output power of wind turbine (WT) is proposed in this paper. A linear

A Novel Mooring Tether for Highly-Dynamic Offshore Applications; Mitigating Peak and Fatigue Loads via Selectable Axial Stiffness

open access: yesJournal of Marine Science and Engineering, 2015
Highly-dynamic floating bodies such as wave energy convertors require mooring lines with particular mechanical properties; the mooring system must achieve adequate station keeping whilst controlling mooring tensions within acceptable limits.

Surrogate Models for Wind Turbine Electrical Power and Fatigue Loads in Wind Farm

open access: yesEnergies, 2020
Fatigue damage of turbine components is typically computed by running a rain-flow counting algorithm on the load signals of the components. This process is not linear and time consuming, thus, it is non-trivial for an application of wind farm control ...

Fatigue loading of tendon

open access: yesInternational Journal of Experimental Pathology, 2013
SummaryTendon injuries, often called tendinopathies, are debilitating and painful conditions, generally considered to develop as a result of tendon overuse. The aetiology of tendinopathy remains poorly understood, and whilst tendon biopsies have provided some information concerning tendon appearance in late‐stage disease, there is still little ...

Non-local energy based fatigue life calculation method under multiaxial variable amplitude loadings [PDF]

open access: yes, 2013
Reliable design of industrial components against high cycle multiaxial fatigue requires a model capable of predicting both stress gradient and load type effects. Indeed, taking into account gradient effects is of prior importance for the applicability of
