Several energy maximization control approaches for point-absorber wave-energy converter (PAWEC) systems require knowledge of the wave excitation force (WEF) that is not measurable during the PAWEC operation. Many WEF estimators have been proposed bas... Read More about Observer-Based Unknown Input Estimator of Wave Excitation Force for a Wave Energy Converter.

Wave excitation force estimation and forecasting for WEC power conversion maximisation (2019)
Presentation / Conference Contribution
Shi, S., Abdelrahman, M., & Patton, R. J. (2019, July). Wave excitation force estimation and forecasting for WEC power conversion maximisation. Presented at IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), Hong Kong

Prediction or forecasting of the wave excitation force (WEF) is required for implementing a power ef ciency maximisation control of wave energy converters (WECs) due to the inherent non-causality of required power take-off (PTO) force. WEF prediction... Read More about Wave excitation force estimation and forecasting for WEC power conversion maximisation.

Hydrodynamic and control optimization for a heaving point absorber wave energy converter (2019)
Thesis
Jin, S. Hydrodynamic and control optimization for a heaving point absorber wave energy converter. (Thesis). University of Hull. https://hull-repository.worktribe.com/output/4221763

The thesis aims at studying the non-linear performance of a designed 1/50 scale point absorber wave energy converter (PAWEC) in heave motion. In particular, designs of the PAWEC geometry and control strategy are considered to optimize the power captu...

Fault-tolerant load reduction control for large offshore wind turbines (2019)
Thesis
Liu, Y. Fault-tolerant load reduction control for large offshore wind turbines. (Thesis). University of Hull. https://hull-repository.worktribe.com/output/4270015

Offshore wind turbines suffer from asymmetrical loading (blades, tower etc.), leading to enhanced structural fatigue. As well as asymmetrical loading different types of faults (pitch system faults etc.) can occur simultaneously, causing degradation o...
