Abstract or Summary
  • The performance of the power take-off (PTO) system for a wave energy converter (WEC) depends largely on its control algorithm. This paper presents an adaptive damping control algorithm that improves power capture across a range of sea states. Validation for the numerical model was performed using data from two sources; sea trail data of a 1:7 scaled model and tank testing data from a 1:33 scaled model. The comparison between this control algorithm and other active control approaches such as linear damping is presented. Short term wave elevation forecasting methods and wave period determination methods are also discussed as requirements for this method. This research is conducted for a novel point absorber WEC, developed by Columbia Power Technologies (COLUMBIA POWER).
