The controller for Archimedes wave swing (AWS) based wave energy conversion (WEC) system is designed in this paper. Based on the model of the AWS based WEC system in the d-q frame of reference, the control strategy of the WEC system under the irregular wave is derived. The AWS based WEC is regulated to be in resonance with the wave by the stiffness control of the linear permanent magnet generator, so that the power extracted from the wave can be improved. Using the control strategy proposed, it is demonstrated that the dynamic performance and the accuracy of the control are improved.
