Abstract
We developed the generator control system by model predictive control methodology, MPTC (Model Predictive Tuning Control), that enables WEC to tune every wave and then yield strictly maximum electric power considering copper loss. The system was implemented at a small test device and this amazing technology was verified practical through tank tests. We also made computer simulator of MPTC for design use. The simulated results for typical configurations of commercial size WEC were those correct the fallacy about viability of wave energy.
