Observer-Based Unknown Input Estimator of Wave Excitation Force for a Wave Energy Converter (2019)
Journal Article
Abdelrahman, M., & Patton, R. (2020). Observer-Based Unknown Input Estimator of Wave Excitation Force for a Wave Energy Converter. IEEE Transactions on Control Systems Technology, 28(6), 2665-2672. https://doi.org/10.1109/TCST.2019.2944329

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.

Learning a predictionless resonating controller for wave energy converters (2019)
