Abstract

A control system (55) is provided for a wave energy device (10) including a rotary absorber (40). The control system (55) can adjust the rotation speed (S) of the rotary absorber (40) based on the velocity (V) of fluid flowing through the absorber resulting from waves in order to optimise the efficiency of the absorber (40).
