Texture analysis for wind turbine fault detection
(Curran, 2016)
Text en actes de congrés
Accés obertThe future of wind energy industry passes through the use of larger and more flexible wind turbines in remote locations, which are increasingly offshore to benefit stronger and more uniform wind conditions. Cost of operation ... -
The use of the dynamic vibration absorber for energy harvesting
(2019)
Text en actes de congrés
Accés restringit per política de l'editorialVibration energy is abundantly present in many natural and arti cial systems and can be assembled by various mechanisms, mainly using piezoelectric and electromagnetic means. In the present article, the electromechanical system ... -
Unscented Kalman filters for estimating the position of an automotive electronic throttle valve
(2016)
Article
Accés obertThe paper presents an application of unscented Kalman filters to an automotive electronic throttle device. The motivation of this study is on estimating the position of the throttle device when measurements of position ... -
Variable structure strategy to avoid torque control saturation of a wind turbine in the presence of faults
(2016)
Text en actes de congrés
Accés obertEvery physical actuator is subject to saturation. It has been well recognized that, when the actuator saturates, the performance of the closed-loop system (designed without considering actuator saturation) may seriously ... -
Velocity-surface stability of a moving charged particle in a controlled electromagnetic field
(2016-07-01)
Article
Accés obertGiven the equation motion of a moving charged particle in a controlled electromagnetic field, this paper proves that its velocity-trajectory motion converges to an specified velocity-surface in the 3-D Euclidean dimensional ... -
Vibration control of hysteretic base-isolated structures: an LMI approach
(2016)
Article
Accés restringit per política de l'editorialSeismic isolation systems are essentially designed to preserve structural safety, prevent occupants injury and properties damage. An active saturated LMI-based control design is proposed to attenuate seismic disturbances ... -
Wind turbine fault detection and classification by means of image texture analysis
(2018-07)
Article
Accés obertThe future of the wind energy industry passes through the use of larger and more flexible wind turbines in remote locations, which are increasingly offshore to benefit stronger and more uniform wind conditions. The cost ... -
Wind turbine fault detection through principal component analysis and multivariate statistical inference
(2016)
Comunicació de congrés
Accés obertThis work addresses the problem of online fault detection of an advanced wind turbine benchmark under actuators (pitch and torque) and sensors (pitch angle measurement) faults of different type: fixed value, gain factor, ... -
Wind turbine synchronous reset pitch control
(2017-06-01)
Article
Accés obertReset controllers are commonly used to smooth the transient response of systems. We use this technique to improve a standard baseline pitch controller for offshore wind turbines (WTs). The introduction of this strategy ... -
Wind turbines controllers design based on the super-twisting algorithm
(IEEE Press, 2016)
Text en actes de congrés
Accés obertThe continuous increase in the size of wind turbines (WTs) has led to new challenges in the design of novel torque and pitch controllers. Today’s WT control design must fulfill numerous specifications to assure effective ...
