Abstract: Subsection control strategy of power generation at high-speed and energy storage at low-speed was used to solve the low efficiency problem of direct-drive wave power generation system based on the fully enclosed oscilla- ting floating wave power generation system． The control of integrated maximum power acquisition was studied com- bining with passivity-based control． In order to avoid the fluctuation and shock phenomena in the process of sub- section control，the energy trajectory of the switching process was planned by using the differential smoothing theo- ry． The simulation results show that the application of subsection control strategy and the differential smoothing theory can not only improve the power generation efficiency but also avoid shock impact．

Key words: wave power generation, differential smoothing, trajectory planning, passivity-based control
