A control-oriented wind turbine dynamic simulation framework which resolves local atmospheric conditions
Z. Feng, Y. Liu, R. Ferrari +1
Wind turbines may experience local weather perturbation, which is not taken into account by the commonly-used wind turbine simulation packages. Without this information, it is extr…
An Economic Model Predictive Control Approach for Load Mitigation on Multiple Tower Locations of Wind Turbines
Zhixin Feng, Alexander J. Gallo, Yichao Liu +3
The current trend in the evolution of wind turbines is to increase their rotor size in order to capture more power. This leads to taller, slender and more flexible towers, which th…
The Proportional Integral Notch and Coleman Blade Effective Wind Speed Estimators and Their Similarities
Yichao Liu, Atindriyo K. Pamososuryo, Sebastiaan P. Mulders +2
The estimation of the rotor effective wind speed is used in modern wind turbines to provide advanced power and load control capabilities. However, with the ever increasing rotor si…
Periodic Load Rejection for Floating Offshore Wind Turbines via Constrained Subspace Predictive Repetitive Control
Yichao Liu, Riccardo M. G. Ferrari, Jan-Willem van Wingerden
Individual Pitch Control (IPC) is an effective control strategy to mitigate the blade loads on large-scale wind turbines. Since IPC usually requires high pitch actuation, the safet…
Blade Effective Wind Speed Estimation: A Subspace Predictive Repetitive Estimator Approach
Yichao Liu, Atindriyo Kusumo Pamososuryo, Riccardo Ferrari +2
Modern wind turbine control algorithms typically utilize rotor effective wind speed measured from an anemometer on the turbine's nacelle. Unfortunately, the measured wind speed fro…
The Immersion and Invariance Wind Speed Estimator Revisited and New Results
Yichao Liu, Atindriyo Kusumo Pamososuryo, Riccardo M. G. Ferrari +1
The Immersion and Invariance (I&I) wind speed estimator is a powerful and widely-used technique to estimate the rotor effective wind speed on horizontal axis wind turbines. Anyway,…
Fault-Tolerant Individual Pitch Control of Floating Offshore Wind Turbines via Subspace Predictive Repetitive Control
Yichao Liu, Joeri Frederik, Riccardo M. G. Ferrari +3
Individual Pitch Control (IPC) is an effective and widely-used strategy to mitigate blade loads in wind turbines. However, conventional IPC fails to cope with blade and actuator fa…
Fast Adaptive Fault Accommodation in Floating Offshore Wind Turbines via Model-Based Fault Diagnosis and Subspace Predictive Repetitive Control
Yichao Liu, Ping Wu, Riccardo M. G. Ferrari +1
As Floating Offshore Wind Turbines (FOWTs) operate in deep waters and are subjected to stressful wind and wave induced loads, they are more prone than onshore counterparts to exper…
Fault Diagnosis of the 10MW Floating Offshore Wind Turbine Benchmark: a Mixed Model and Signal-based Approach
Yichao Liu, Riccardo Ferrari, Ping Wu +3
Floating Offshore Wind Turbines (FOWTs) operate in the harsh marine environment with limited accessibility and maintainability. Not only failures are more likely to occur than in l…
Fault Detection of the Mooring system in Floating Offshore Wind Turbines based on the Wave-excited Linear Model
Yichao Liu, Alessandro Fontanella, Ping Wu +2
Floating Offshore Wind Turbines (FOWTs) are more prone to suffer from faults and failures than bottom-fixed counterparts due to the severe wind and wave loads typical of deep water…
Feedforward control for wave disturbance rejection on floating offshore wind turbines
Mees Al, Alessandro Fontanella, Daan van der Hoek +3
Floating offshore wind turbines allow wind energy to be harvested in deep waters. However, additional dynamics and structural loads may result when the floating platform is being e…
