  This paper describes the detailed analysis for the design of a linear
generator developed for a Surface Riding Wave Energy Converter (SR-WEC), which
was designed to improve energy capture over a wider range of sea states. The
study starts with an analysis of the power take-off (PTO) control strategy to
harness the maximum output power from given sea states. Passive, reactive, and
discrete PTO control are explored. For the random wave excitation and limited
sliding distance of the generator, the discrete strategy provides the highest
average power output. The paper discusses the sizing requirement for the linear
generator. Based on the force and power rating of the system and the
application requirements, a slotless permanent magnet tubular generator is
designed for the wave energy converter.
