This paper presents an innovative technique for evaluating the performance of direct-drive power take-off systems for wave energy devices using simulated force and velocity profiles. The performance of a linear generator was evaluated in a realistic operating condition using the results from a coupled model of a taut moored, dual body, and wave energy conversion system as position input for Oregon State University’s wave energy linear test bed. The experimental results from the linear test bed can be compared with the predictions of the simulation and used to evaluate the efficiency of the generator.
