Abstract
Motion of wave energy converters (WECs) is usually exaggerated as a consequence of the application of control
strategies for energy absorption maximisation. With the aim of
preserving the physical integrity of the devices, constraint handling mechanisms, as part of the underlying control strategies, are
considered a key component. Recent developments in wave energy
control include a linear time-invariant-based controller presented
in the literature as LiTe-Con, which provides a simple constraint
handling mechanism. However, this handling method can lead to
conservative performance in certain scenarios. To overcome such
limitations, this study presents a time-varying methodology for
an online adaptation of the constraint handling mechanism in
LiTe-Con, while preserving its original simplicity and efficiency.
Experimental assessment of the presented control methodology is
provided in this study, using a broad range of operating conditions. Results show that the presented control strategy (LiTe-Con+)
exceeds the performance achievable with the original LiTe-Con.
Additionally, the benefits of LiTe-Con+, such as low computational
demand, technical versatility, and impressive performance level are
highlighted.
