Abstract

Pitch control is one of the most common approaches to regulate the captured power of the wind turbine when the wind speed exceeds the rated value. However, the performance of power regulation on the offshore floating platform is often disturbed by the complex deep-sea wind-wave environments. This paper proposes the Nonlinear Extend State Observer (NESO)-based Nonlinear Proportional-Integral (N-PI) pitch control, which considers the influences of extreme wave dynamics in Tension Leg Platform (TLP)-based Floating Offshore Wind Turbine (FOWT). The model of the TLP-based FOWT is investigated by developing a typical two-mass model of a wind turbine and a nonlinear dynamic model of the corresponding platform. The simulation results show that the NESO-based N-PI provides improved robustness against the drastic variation of the wind speed and wave dynamics compared with the conventional Proportional-Integral (PI) pitch control and Gain-Scheduled Proportional-Integral (GSPI). The peak value of the twist angle is also reduced under the proposed control scheme, and the performance of releasing mechanical stress is improved compared with the conventional PI pitch control and GSPI control.
