This paper discusses the maximum energy converting control for the wave energy converter having two floating bodies subject to irregular incident waves. It is already known theoretically and experimentally that this system has high energy converting efficiency for regular waves. First, the irregular incident waves which are expected to arrive at the floating bodies are obtained based upon our previous procedures for one-floating-body-type energy converter and maximum energy converting conditions are obtained for this two-floating-body-type energy converter. Then, the difference between the predicted behaviors of the floating bodies due to predicted incident waves and the real behaviors of them subject to the arriving waves is fedback using the PD control law to maximize energy converting efficiency. It is shown by numerical simulation that the energy converting efficiency is improved about 10 %.
