Wave energy is one of the most hopeful renewable energies. A floating point-absorber with an oscillating body type conversion system will be lower cost and suitable for the offshore powerful wave energy. Although a resonant control strategy is suitable for the oscillating body type converter, it is practically difficult to use because of the mechanical and electrical system limitations. It is important to design an optimal control strategy in the limitations. In this study, a new concept with detuned parameters for a resonant control system is discussed by using a time-domain numerical simulation of the converter. It is presented that the maximum displacement of the converter is reduced by the detuned parameters for the resonant control.
