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.

Integrated Fault-Tolerant Control for Close Formation Flight (2019)
Journal Article
Liu, C., Jiang, B., Patton, R. J., & Zhang, K. (2020). Integrated Fault-Tolerant Control for Close Formation Flight. IEEE Transactions on Aerospace and Electronic Systems, 56(2), 839-852. https://doi.org/10.1109/TAES.2019.2920221

This paper investigates the position-tracking and attitude-tracking control problem of close formation flight with vortex effects under simultaneous actuator and sensor faults. On the basis of the estimated state and fault information from unknown in... Read More about Integrated Fault-Tolerant Control for Close Formation Flight.

Decentralized Output Sliding-Mode Fault-Tolerant Control for Heterogeneous Multiagent Systems (2019)
Journal Article
Liu, C., Jiang, B., Patton, R. J., & Zhang, K. (2020). Decentralized Output Sliding-Mode Fault-Tolerant Control for Heterogeneous Multiagent Systems. IEEE Transactions on Cybernetics, 50(12), 4934-4945. https://doi.org/10.1109/TCYB.2019.2912636

This paper proposes a novel decentralized output sliding-mode fault-tolerant control (FTC) design for heterogeneous multiagent systems (MASs) with matched disturbances, unmatched nonlinear interactions, and actuator faults. The respective iteration a... Read More about Decentralized Output Sliding-Mode Fault-Tolerant Control for Heterogeneous Multiagent Systems.

Fault-tolerant load reduction control for large offshore wind turbines (2019)
Thesis
Liu, Y. (2019). Fault-tolerant load reduction control for large offshore wind turbines. (Thesis). University of Hull. Retrieved from 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...
