Abstract: Based on the research of the power capture optimization method for the direct-drive wave power generation system，a state switching control method based on a linear generator was proposed in this paper． Based on the characteristic that the speed of the linear generator in the no-load state is higher than that in the power generation state，the linear generator is controlled to switch between the no-load state and the power generation state，thereby increasing the speed of the linear generator in the power generation state． Therefore，the captured power is further improved． The results show that，compared with other power capture optimization methods，the proposed method has excellent performance in power capture．

Key words: direct-drive wave power generation system, power capture optimization method, state switching control method
