This paper presents a novel method of estimating ocean waves by measuring current outputs from the Archimedes Wave Swing (A WS) wave energy converter (WEC). The wave period and height are crucial information to maximize the power output from the A WS. However, since the A WS is installed on the seabed, additional sensors and buoys are required to obtain the ocean wave information. The extended Kalman filter (EKF) is applied to obtain the states of the ocean wave by measuring the generator current in the a -f3…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
