A Feedback Control Loop Optimisation Methodology for Floating Offshore Wind Turbines
(MDPI, 2019-09-10)
Wind turbines usually present several feedback control loops to improve or counteract some specific performance or behaviour of the system. It is common to find these multiple feedback control loops in Floating Offshore ...
On the links between limit characteristic zeros and stability properties of linear time-invariant systems with point delays and their delay-free counterparts
(Hindawi Publishing Corporation, 2004)
We investigate the relationships between the infinitely many characteristic zeros (or modes) of linear systems subject to point delays and their delay-free counterparts based on algebraic results and theory of analytic ...
An Advanced Control Technique for Floating Offshore Wind Turbines Based on More Compact Barge Platforms
(MDPI, 2018-05)
Hydrodynamic Floating Offshore Wind Turbine (FOWT) platform specifications are typically dominated by seaworthiness and maximum operating platform-pitch angle-related requirements. However, such specifications directly ...
Using Multiple Fidelity Numerical Models for Floating Offshore Wind Turbine Advanced Control Design
(MDPI, 2018-09)
This paper summarises the tuning process of the Aerodynamic Platform Stabiliser control loop and its performance with Floating Offshore Wind Turbine model. Simplified Low-Order Wind turbine numerical models have been used ...
Modified active disturbance rejection control scheme for systems with time delay
(IET, 2023-09)
Active disturbance rejection control (ADRC) has been gaining attention in recent years and has shown its performance in multiple applications including non-linear ones, without the need of accurate models. Despite the good ...
New Generation Compact Linear Accelerator for Low-Current, Low-Energy Multiple Applications
(MDPI, 2022-04-19)
A new compact linear proton accelerator project (named LINAC 7) for multiple low-current applications, designed and built in-house at the Beam Laboratory of the University of the Basque Country (UPV/EHU) is described. The ...
Numerical optimization based control design for a ferromagnetic shape memory alloy actuator
(Elsevier, 2021-11)
Ferromagnetic shape memory alloys (FSMA) based actuators are able to get very good precision, allowing, indeed, under nanometer positioning applications. To get those precisions, a good controller is needed, and different ...
A novel python-based floating offshore wind turbine simulation framework
(Elsevier, 2024-02)
The expansion of floating offshore wind brings the industry closer to achieving commercial viability. However, the challenging environment characterised by strong winds, waves, and currents, along with the growing size of ...
