A Comparison of Soil Structure Interaction Models for Dynamic Analysis of Offshore Wind Turbines
(2020)This paper compares the dynamic response of an OWT structure where the below ground pile-soil behaviour is modelled using (i) the conventional API ‘p-y’ approach and (ii) the ‘PISA’ approach. A nonlinear aero-elastic code ... -
Flow in a large wind field with multiple actuators in the presence of constant vorticity
(2022)Study of wind farms is an area of active research. Researchers have proposed simplified wind farm models which define the wake structure in a wind farm and how they affect the performance of the wind turbines. Interestingly ... -
Fluid inerter for optimal vibration control of floating offshore wind turbine towers
(2022)This paper proposes the use of a tuned mass damper fluid-inerter (TMDFI) for vibration control of spar-type floating offshore wind turbine towers. The use of an inerter in parallel with the spring and damper of a tuned ... -
Mitigation of Wind Induced Accelerations in Tall Modular Buildings
(2022)This paper compares two methods of mitigating wind induced vibrations in tall modular buildings. Tall buildings experience wind induced motion which can result in serviceability and habitability issues associated with ... -
Multi-resolution wavelet pitch controller for spar-type floating offshore wind turbines including wave-current interactions
(2020)This paper proposes a wavelet multi-resolution based individual pitch control strategy for spar-type floating offshore wind turbines (FOWTs) and investigates its performance under joint wind-wave-current loads considering ... -
Nonlinear model predictive control to reduce pitch actuation of floating offshore wind turbines
(2020)Modern-day wind turbines use active pitch control to reduce mechanical loads on the turbines in addition to regulating generator power. These control algorithms increase blade pitch actuation, primarily to reduce the 1P ... -
A Review of Rapid Distortion Theory
(2022)With the depleting non-renewable fuel sources like coal and an ever-increasing demand for energy, we need to start looking into renewable energy sources. These are of paramount importance for a sustainable and green future. ... -
Structural damping estimation from live monitoring of a tall modular building
(2023)The damping ratio is a key indicator of an individual structure's susceptibility to dynamic loads, including the level of discomfort experienced by the occupants of a tall building subjected to wind loading. While ... -
Vibration control of spar-type floating offshore wind turbine towers using a tuned mass-damper-inerter
(2019)This paper investigates the use of a passive tuned mass‐damper‐inerter (TMDI) for vibration control of spar‐type floating offshore wind turbine towers. The TMDI is a relatively new concept as a passive vibration control ... -
Wavelet‐based individual blade pitch control for vibration control of wind turbine blades
(2019)This paper proposes a novel individual blade pitch control strategy with the objective of reducing blade vibration. A wavelet linear quadratic regulator (LQR) control algorithm, which is an advanced modification of the ...
