Abstract

This paper analyzes a compensating control strategy for stable energy output of the novel direct drive wave energy generator. We propose a compensating control structure based on the unstable second-order linear dynamics for the direct drive wave energy generator, and the dynamics are derived by the on-line system identification method. In the control strategy, we design a servo compensator located at the forward path, in order to cancel the periodical disturbance effect from sea wave energy actuation, serving as a mechanical power source as well. The stability compensator is combined with the local feedback to ensure the generator to track the desired static constant commend precisely. Finally, we highlight the effectiveness of the control strategy through the simulation of the direct drive wave energy generator, and analyze the performance of the proposed control scheme.
