Passive Model Predictive Control on a Two-Body Self-Referenced Point Absorber Wave Energy Converter

Wave energy is nowadays one of the most promising renewable sources; however, wave technology has not reached fully-commercial stage, yet. One key aspect to achieve this goal identify an effective control strategy for each selected Energy Converter (WEC), in order extract maximum from waves, while respecting physical constraints device. Model Predictive Control (MPC) can inherently satisfy these requirements. Generally, MPC formulated as a quadratic programming problem with linear (e.g., on position, speed and Power Take-Off (PTO) force). Since, general case, technique requires bidirectional power flow between PTO system grid, it similar characteristics reactive control. This means that, under some operating conditions, losses may be equivalent, or even larger, than yielded. As many WECs are designed only allow unidirectional flow, necessary set nonlinear constraints. makes optimization significantly more expensive terms computational time. work proposes two strategies applied two-body point absorber that address issue different perspectives: (a) adapting formulation passive loading strategy; (b) flow. The results show alternative proposals have performance time compared regular obtain considerably control, thus proving good option systems.
