✦ Synopsis

This paper studies reactive control of wave-energy devices in irregular waves. Estimates of future velocity of the primary energy converter are based on a time history of past velocity measurements, and prediction of incident waves is not attempted. Time-domain computations for a single-degree-of-freedom oscillating water column in irregular waves reveal that control is not optimal; but would enhance efficiency at low peak frequencies where energy-rich swells predominate, and allow appreciably smaller devices to fulfill a given power requirement.
