520 ## - SUMMARY, ETC.
Summary, etc. In this thesis, we present a quick long-term reactive loading control for heaving buoy wave energy converter. The control is achieved by introducing an external continuous variable sti ness that is connected to the buoy to tune its natural frequency. The external sti ness is connected to the buoy through a continuous Vbelt drive to change its e ect on the buoy. This control maximizes the oscillation amplitudes; hence, maximizing the power absorption e ciency by achieving near-resonance operation. Analytical results show a promising power absorption increase as compared to other control techniques. Experimental results, for an equivalent vibrating system, prove the concept of the control operation
