Despite the favourable energy conditions in the Argentine sea (South Atlantic Ocean), the country has not yet actively participated in the development and utilisation of wave energy resources. Control co-design (CCD) is a novel controlaware design paradigm that integrates the energy-maximising control from early stages of system design, allowing for optimisation driven by the considered control strategy to achieve an overall optimal design. In this study, considering an overall control-aware design perspective, a wave energy converter system is specifically tailored for the Argentine sea conditions, analysing different WEC structural configurations (geometry and dimensions). The performance of different control structures, including a spectral-based control methodology and a reactive controller, are assessed for each configuration. Realistic operating conditions, specifically tailored to the ocean wave modes prevalent in the Argentine sea, are taken into account during the performance analysis. The results obtained from the study are thoroughly discussed, highlighting the advantages and disadvantages of the considered control strategies in the context of the Argentine sea.
