Abstract: In this paper, the control strategy of the generator side of the direct-driven permanent magnetic synchronous generator(PMSG) system is investigated for Offshore Wind Turbines(OWTs). A hybrid control method that combines a repetitive control and T-S fuzzy PID control is proposed to stabilize the output power. For the current and speed loops of a direct-driven PMSG system, Proportional-Integral(PI) control design based on internal model theory is used for the current loop and the speed loop adopts T-S fuzzy PID control scheme. Furthermore, two wind speed sequences are used to simulate and analyze the proposed system. The proposed hybrid control strategy is evaluated through numerical simulations that incorporate a realistic model of the direct-driven PMSG, which is built in MATLAB/Simulink environment.
