The paper considers a reference-based control system for heaving wave energy converters. The proposed controller comprises two parts: lower level part (LLP) and higher level part (HLP). The HPL generates the buoy's velocity reference with the objective to maximize the power absorption with the constraints in the maximum control force and the power take-off device's utilization index. The index is...
This study considers maximising conversion between the mechanical and electrical powers for heaving point absorbers (HPAs). The objective is implemented by generating the buoy's velocity reference by designing the intrinsic resistance. The authors designed the intrinsic resistance using a rapid procedure involving the mechanical and electrical models of HPAs. The electrical power conversion can be...
Developing simple, economic, and efficient electrical power conversion systems for wave energy converters (WECs) is an on-going research topic. This paper considers a simple resonance circuit to maximise the ac–dc power conversion of a permanent magnet linear generator (PMLG). To implement this circuit, the PMLG model parameters were obtained. In this paper, we developed a procedure for designing...
