Abstract
In this paper, the current tracking control problem of direct-drive wave power generation system disturbed by complex environment is solved by designing finite-time controller(FTC) and backstepping sliding mode controller (BSMC). In order to realize the maximum power tracking control of the directly driven wave energy converter (DWEC), a fixed-time observer (FTDO) is designed to quickly compensate for environmental disturbances, and a backstepping sliding mode control strategy based on FTDO (FTDO-BSMC) is proposed to accurately track the current. Finally, Numerical simulation and comparison demonstrate the feasibility and superiority of the proposed scheme.
